Is there any reason to pay the fee for Experts-Exchange and ask questions there too?
I actually never liked Experts-Exchange anyway.
StackOverflow is free, looks better, has better functionality and is simple.
I think that StackOverflow will ground the future of online support / help communities in general. It brings fluent a fluent feeling of usage without stubbornity. (yeah, that word doesn't exist, but anyway ;p)
Also, with the time StackOverflow will have way more hits on google or other search engines than Experts-Exchange ;-)
People at Experts Exchange should read Joel's article The Day My Industry Died. This is exactly what SO did to EE :)
