I like that it's super easy to use, you can comment by clicking "like" or "disagree", they have some cool templates for your comments too! It would be nice if there were more people using this software so we could get feedback from them about what features are lacking/what is working well with their platform as opposed of just posting our own thoughts here in forums (which isn't always helpful).
Try out different things until something works best - maybe start small first? We've been able post all kinds of projects into one place without having multiple accounts set up & linked together which has saved us tons time compared when doing project work alone before getting reviewed through Github etc..
