Thoughts After day 3 on pump.io:

 Real conversations, thanks @evan for freeing us from 140c limits
 Federation galore, can't wait till a pump.io instance is as drop in ready as postfix/exim
 Control, can send to: person, list, followers, public.. nice fine grained control of what i share to whom

All things considered I am really loving pump.io and can really see a lot of potential. I'm even inspired to do some hacking myself. Yes, the clients and web UI are a bit buggy. Yes the features aren't fully fleshed out. But it's early days and things only get better from here.. Hang on and enjoy the ride!!
