Mesh is a team based social collaboration platform
Works great with lots of features commonly found elsewhere but all in 1 package. Site is extremely fast even on mobile.
Pros:great idea. makes it easy to connect directly with like minded people (devs and techie types)
Cons:slightly ugly design, not 4k ready.
Prototypr
I have no connections on Mesh, and it's hard to discover them with search - especially if they're not on it yet. An invite system would really help grow the product! Look at how https://refind.com/ and medium.com work, sign up with your twitter account and automatically you have a network.
Pros:Social network that's actually productive
Cons:I have no friends
