This is my project http://www.mediawiki.org/wiki/User:Making-it-yours for GSOC - 2013, which I hope haven’t interested you.
Recently, I encountered with an analogy for my project which I wish to discuss with you so that I can persuade you. Head to this https://play.google.com/store/books and select a free book ( say Pride and Prejudice). Select some text and see how elegantly we can do operations I wish Wikipedia must have but not limited to. I can't get the technology they use for this. I wish you could figure out. Please help me with understanding it.
Hope it makes you love it.
Kind Regards
Vishal
