Thanks @fharper really good idea :)
I would add it at least so it's more in focus @frgfm @charlesmindee wdyt ?

I was thinking about reorganizing the icons as well !
Excellent idea @fharper 👍

For the sake of visual aspect, I'd suggest to go for a color matching Slack company guidelines while staying similar to other icons from the README. Something like this for instance ?

Also I think there is a mistake in the slack URL you put (it looks like the internal one, not the community), I put the invitation URL in the above button ☝️

@frgfm: the link is good, and I prefer the one you created (the flat design) but it won't match with the other one. I guess you'll update them like this?

[frgfm]

Oh I hadn't checked that there is a redirect in the URL 👍
We'll update badges on another PR, that one is a great addition anyway !
