I find that having multiple accounts don't give you much advantage and you need to be good at multi-tasking. Anyway, I prefer to focus my energy on one account to play on bustabit as you need to be fast at times.
Multiple accounts gives you an ability to test different strategies on the same game history, which might be very handy.
There really needs to be some archive limit on Bitcointalk to prevent people who are bumping these year old forum posts.
Actually there is a soft-warning that says "This thread is over 90 days old" but people ignore that and post anyways to these irrelvent topics of today. This category needs some type of moderation from time to time.
