"All Day, E'ery Day"

Comments: It is so helpful to use with remote teams. I use it daily for two different employers, and actually convinced my main employer (a government agency) to start using slack. Slack allows teams to communicate easily and quickly, sharing links and documents all through the app. It also allows for camaraderie and fun, an important part of every workplace, even when you aren't physically with your team. The absolute most convenient thing about Slack is that you can use the desktop and mobile version, and someone can ask you a question, you can answer it, and work can move forward efficiently. For teams with people in different time zones and different work hours, this is incredibly helpful while texting and email sometimes don't cut it. For people who are outside of traditional cell service, sometimes I can connect to Slack even when text/calls are not going through.

Pros: I love how easy it is to communicate with people, and the informal format the encourages communication rather than dissuades it. People might be less inclined to send an email or call because they are interrupting your work, but slack doesn't have that feeling at all.

Cons: The limit on shared images after you hit a certain threshold with the free version - to be fair, this is a minor inconvenience at most and just another reason to pay for it!

"Great Business Continuity Tool"

Comments: It has been a great experience using Slack. It is a valuable tool and I really like how we are able to collaborate as a team and make it seem as if we are still working together in the office.

Pros: 1:1 Chat - Ability to have 1:1 conversations with team members. Useful when working on a project together.
Team Collaboration - Ability to bring a project together and share with a team.
Group Chat - Ability to have one area/space where the team collaborates, shares ideas, and works together to communicate issues.
Bot Integration - Ability to integrate various tools and bots that can make the day easier. Ability to integrate to web conferencing tools like Zoom, Webex, Teams. Ability to create to-do lists, track time, etc.
Manage Team - Great way to manage a team who is working remotely in various geographic locations.

Cons: Still trying to work around our SSO integration - This is mostly an internal bug we are trying to work on, but it would be nice if we can make Slack to work for a single sign on experience.

"Slack is essentially advanced texting for business users"

Comments: I started using Slack because my client required it. I find that it cuts down on my email dependence but I'm often frustrated when attempting to compose a message without standard elements such as tables, inline images, etcetrera.

Pros: I like the ability to stay in touch with our users via whatever device I'm currently using. For example, I can respond from my home computer, tablet, work computer or via my phone. I especially like the ability to be notified of a new message via my phone where I can read the message on the phone but can step over to my laptop to reply. I also appreciate the ability to add an email thread to a Slack Channel by simply adding a slack email address (each channel has a unique email address) to the CC field when I reply.

Cons: The biggest con for me is the extremely limited amount of formatting available to Slack messages. I can make a font bold and add links to files/images but I really miss the rich text features many similar apps provide. It's also frustrating to need to keep typing adding the user name(s) when I'm responding to a message. I'm assuming that this is by design but it would really be nice to be able to "Reply All" to a conversation thread. The desktop Slack application (running on Windows 10 Pro) has a "clunky" feel to it. It's written with a framework that allows the Slack developers to write HTML and JavaScript code that is essentially compiled into a Windows application and it definitely shows. Something as simple as selecting text is counter-intuitive (until you realize that it's essentially a web page mascaraing as a Windows application.

"Great for charitable organizations (because it can be free). Powerful. But expensive!"

Comments: Push notifications and alerts have been helpful. We are able to get important information out to our team very quickly, and we are able to "thread" the information so that only certain groups or certain topics are discussed in certain "channels" or "threads."

Pros: Slack is made free for basic functions for charitable organizations. For this reason it can be a great option for charitable organization. It has powerful features, including video conferencing, file sharing, phone and web app integration, and file sharing. It also has cross-platform integration allowing connectivity between multiple different products, including Google and Microsoft products and IFFFT.

Cons: It is not cheap at all for even a small organization (unless your organization qualifies for a free subscription). There are limits to the number of users in a video conference.

"An industry leader for a reason"

Comments: I love slack and it is always getting better. Finding my chats, creating channels, and adding integrations are easy. I can’t recommend it for business enough. It’s so fun that I am trying to find other uses for it just so I have an excuse to use it.

Pros: Slack has become the industry leader in workplace communication and for good reason. It makes for a flexible place to have contextual conversations and integrates Into your workflow by easily allowing tools to integrate Into the application. From shopping carts to service monitoring alerts to team polls, there are integrations for just about everything. These integrations also allow meaningful, yet simplified, interactions so I don’t always have to leave The context of my conversations.

Cons: The largest problem is cost as well as limits in how I can leverage Slack For both work and for non-work related communication. It wasn’t built for non-work communication so I can’t truly complain. But I would love to see some focused paradigms show up in the ecosystem to make it so I don’t have so many chat applications. One other issue is the confusing of finding and managing my custom web hooks. As often as I use it I always end up spending 5 minutes on the site trying to figure out what we hook integrations I have and where to reconfigure them.
