How many of you know about Packtpub and its free learning program?
Everyday you get a nice ebook on programming :)

Now THAT is helpful beyond words.

Yea, I follow @java on Twitter and they almost daily tweet about a free ebook(downloadable within 24hrs or so). Really helpful it is I must say and the only helpful tweet that makes sense by java on Twitter is about that.

Edit: Not the Java devRant user, but actual Java account on Twitter.
