Twitter Founders New Medium (Examples): Personalized BBS as a Trend? Will "Medium" Be a Hit?

Will "Medium" at Medium.com be the new Pinterest?
by the founders of Twitter - at Welcome to Medium

examples --

When I was a kid, Evan Williams etc. - nostaligic photos and "clever" texts
This Happened to Me, Evan Williams etc. - "not so clever" texts
The Obvious Collection, Biz Stone - improving the world
The Writer's Room, Steven Johnson - memory and procrastination

This is essentially a new twist on information "bulletin "boards" -- BBS in the old days (there is really nothing new under the sun) -- but you just never know what people are going to find interesting or useful.

Is personalized BBS in the trend?

Williams has a stellar track record as founder of Blogger and Twitter.
He tends to come up with things that people ultimately find useful, even if not used the way originally intended, so that one is curious to see what this will lead to.

Still in development and by invitation only.
