Awesome; does everything it should

I have a love/hate relationship with chat applications, but I think Slack kind of sets the bar for them at this point. The app does basically everything I could ask of it, and it’s quite responsive.

I’ve also noticed lately that there are lots of times I think “man it’d be nice if Slack did ___”, and then before long I open the recently-updated app and that feature appears. (A good example of this, I think, is the way you can now set a status in Slack to expire after a certain amount of time, which is great for something like a ‘working remotely’ status that you want to disappear at the end of the day). This is a tendency that I’ve seen in only a handful of apps/services, and I think it shows a high degree of responsiveness to the needs of their customers, which is awesome.

Great tool

We use in our small law office. We had to write some of our own "best practice rules" (like phone message channels only get phone messages, no gifs in general, snooze when you aren't answering) but it's been a great tool for our office. Easy way to be sure you're keeping up with your team without getting in to email all the time. We love it because if person a has a question for person b, a send the question and b gets to answer when they have the time in their day. Minimize interruptions while also allowing the person with a question to say it when they're thinking about it. We love slack. It's AOL instant messenger for professionals. I do wish it was easier to upload images etc without the comments being a weird title.

Becoming my go to comm app...

First, my rant (feel free to skip):
I was not pleased when Microsoft purchased Skype, and my fears were increasingly justified as I saw version release after version release further thrash GUI conventions (if Microsoft made light switches, down would turn the light on and up would turn it off...). Finally, the family decided to stop using Skype for our domestic and international communications needs. We switched to Slack...

Second, my review:
It took some getting used to, but Slack is now our family communication hub... we’ve got channels for making travel plans, sharing recipes, and even communicating while playing Minecraft (yes, I know, Microsoft...).

Slack has not only replaced Skype, but is quickly replacing our need to use generic texting and e-mail. I’m still very fond of Discord, but who knows...!?

I highly recommend slack. Delve into it. Learn it well, and perhaps you too will adopt it as your one comm app to rule them all!

5-stars. Hands down.
Slack people: promise me you’ll never sell this to Microsoft when Team simply doesn’t grab enough market share, and they come knocking. Pretty please...
