great form builder, easy to use and they keep adding features, my team an I really enjoy using it!

Slack runs the risk of getting bloated like Evernote did. If you use it as research base, integrate the key features, leave the rest out and find out the one or other magic sauce for teamwork chat specificall you will be more competitive and resource efficient. Please don't try to be heros or bloat this up. The 20/80 Copycats for Free and add some valuable stuff on your own and that's all one...
