I have been maintaining http://tamilblogs.com for sometime. This is a blogs aggregator which aggregates over 650 blogs written in my native language tamil . Initially I created tamilblogs.com using an opensource blogs aggregatory - gregarius . Later due to performance issues I switched to another opensource blogs aggregator called lilina.
Later I added mysql database support to tamilblogs using code from another similar opensource project lylina. Some of my tamil blogger friends have requested me for the complete sourcecode of the software used in tamilblogs. After few more such requests I thought opensourcing this tamilblogs software would be helpful to many.
Thus was born the new blogs aggregator by name tamilblogs here: http://code.google.com/p/tamilblogs/
Right now one of blogger masivakumar has joined me in this project. I hope many more will join and enhance this project.
