Share buttons

Added buttons: Finally added tweet, like, share, burp and fart buttons (LOL) to this humble blog in blogger. So much info around there but not all of them are up to date, it was hard to find the correct information.
Got some info from here, here, here and here put the code inside my blog in the footer :)
Which one was the easiest ?
The winner is LinkedIn besides it looks great :) but GooglePlus was almost as easy as the winner.

Which one was the most difficult ... ?
Facebook, Ohh how I hate Facebook!

Twitter is OK :)
