If you battle on BlogExplosion, here is a simple rule of thumb to estimate your minimum worth:
If you are a smart guy or girl - 5 votes
If you are a funny guy or girl - 6 votes
If you are a pretty and funny girl - 7 votes
If you are funny guy with pictures - 9 votes
If you are a pretty, funny girl with pictures - 10 votes
If you have friends who will always vote for you - priceless
P.S.: A few clarificatons:
1. The above post is not to be taken seriously.
2. I am no expert in the BotB and any advice from me will probably not help you.
