I'm a part of a ton of Slack communities but I'm active in only a handful.

Slack works to its fullest only when it is implemented in a team and everyone's supposed to use it for communication. Slack could/should improve on making the communities on it better by adding relevant features.

As a remote designer, this is a must have. I'm always contactable and available. Super easy way to also have quick calls and communicate with other team members on different teams.

I love using emails less.

UX Improvement: Having conversation tabs similar to any modern web browser so important conversations don't get lost in the left menu drawer.

New Feature: Calendar. This would hopefully kill our company's horrific use of Microsoft Outlook once and for all :-)

Transformed the way we deal with freelancers and sped up our communication exponentially. It means that we can have reactive conversations, essentially 'spinning around in the chair and chatting,' when we think of something.

We use Slack at 99designs for all internal comms and have even implemented a Slack plugin for customers on our site to help manage their design contests. It's a great communication tool, offering the ability to create various chat rooms for different purposes (we have serious ones like #Announcements and silly ones like #dadjokes) and communicate across our international offices. We also recently started using Slack's video chat feature and definitely like it more than Google Hangouts - better connectivity for sure.

Overall this product works smoothly and the updates the developer releases are meaningful and truly addresses a lot of the bugs I generally see the week before a release. They true stay on top of the product and make a great interface for user interaction.

I use this one everyday, will not be installing the native app for my desktop and I really wish this was available for mobile as well. As a web technology addict, I'd say this is one beautifully made web-app and it totally does what it needs to do. Even better.

Well, it's Slack. You know what it is. It's pretty cool, eh? Still crossing fingers for a smoother Slack desktop experience, but otherwise it's a marvelous thing.

It's a great app for chatting with your team (workmates). What I like it has different channels you can create and post relevant chats (like marketing, sales, product dev etc). Also, you can integrate this with other tools like for eg. google analytics and let them send a notification message to a specified channel in case of anomalities etc. Great alternative to skype for business!

Slack is a great communication software that can totally eliminate internal email communications. Also let's not forget about the huge marketplace behind it, which enables insane amount of intergration.

This is one of the bast conversation tools I've used personally.

Fast & simple with a different ways to express your thoughts.

Fancy code & snippet tools, but sometimes link preview feature can be hell :(

We use Slack at work! We are really satisfied with the tool - so we directly integrated eyeson in Slack ;) https://www.producthunt.com/search?q=eyeson+for+slack

Slack is awesome! Very well thought-out with tons of short cuts, a great API and a pretty robust app directory to enhance the experience in all kinds of ways, some fun, some serious. Definitely integrates with almost all major platforms and the apps for Android and iOS are fantastic as well. No complaints here.

Interesting concept but the channels can get pretty confusing and there were many miscommunications between our organization because people couldn't use it coherently. Maybe I'll try it again sometime but I need a break.

Slack also has a lot of good integrations with other softwares make our day-to-day work super easy. The option of free slack also gives the opportunity to connect with people outside of org.

great for both work , small teams and even for creating communitys

We're a Saas company and we use it every single day for ALL communication. It is just a great tool.

Saying that Slack will replace email communication channel, wouldn't be an overstatement :)

It's a flashier version of HipChat, but not demonstrably better necessarily. Although I do like how shared Google documents show up in chats.

Adding more voice integrations would be amazing.
