Quote from retaildaytrader:
#1- You do not know who is behind them.
Why do you care? There are 2 kind of blogs: useful and useless
It matters not who writes it. The worst blogs are the inconsistent ones, because they are a coinflip basicly. You can follow a good blog and you can fade a bad one, but an inconsistent one is useless...
But the bottomline is that the writer doesn't matter, the trackrecord does....
