It is a Forum site and when i checked in analytics the percentage change shows "N/A". In alexa when i checked my site every one week rank is increasing. Check my site in signature.
Google Analytic report are not that accurate which it may not track the traffic correctly with open source and so on. And the traffic is not real time which the traffic track result maybe slow. Bounce rate the lower the better. Bounce rate is people do not stay at your website in the minimum of time. It mostly happen when people feel that in risk to open your site or unable to found what they want in your website.
I get 60%, a friend who run a few successful sites tells me that’s pretty normal. Not really sure how to reduce that as most of my traffic is to read a news article and then leave.
35%-60% is acceptable i think, when website's bounce rate is on upward direction everyday, it means visitors paid less time at website than before.
