Joining the heard...

This is my first post and Iam not really very clear abt this blogging and how it serves any purpose... hope people who have a better understanding will enlighten me with that part. A good friend told me that it has many advantages but i dint really grasp what those were. Anyways this is me joining the millions of folks doing what iam doing now....blogging. i am joining this heard in the sole hope that this heard must be headed towards a sensible purpose or at least a purpose worthy of the time and the effort.
