I have tarted about a lot of BBing/fitness sites, and this is my take on it.
As far as general chat goes, this board is very quick moving with a lot of people posting with a much higher level of intellect than a lot of other boards (unless of course you want to use your brains for my second listed point below)
There are two or three other sites that have fairly active chat if you want to talk about
- gossip about professional BBers/MMA
- completely flame and rip into other people
- be a complete and total science boffin discussing biochemical pathways and latest research papers (ok this is two slower moving sites)
- interact with teenagers who think they know it all and have no experience of the world (think youngguns)
