I “unfollowed” all Linux distros as they didn’t give me much useful information, I’m still following CouchDB, Cassandra, and MongoDB, so far their tweets are kind of helpful.
Also I subscribed to Cassandra’s user mailing list, lots of interesting topics there.
After playing with twitter for couple of days by updating my status of “leaving office” or “arriving home”, I decided to play with twitter “by mouse” instead of “by keyboard”, which means I will stop tweeting, but start to follow others to get the info I want.
What I’m follow now – all Linux distros (Fedora, CentOS, openSUSU, Ubuntu, etc), and some nosql stuffs like Cassandra and CouchDB. I will keep looking if there is anything else I can follow.
