I came across this forum while reading a rss feed for a tech blog. I’ve referenced it many time. The feed for the forum itself was too active, but doing a search for a specific topic or tag has provided helpful information. It has a nice format, and there are linux questions/answers too. The answers are rated, so the most helpful flow to the top. The site: Stack Overflow
At the bottom of the web page are links to:
Super User
Server Fault
with similar formats.
Just passing it on as a potential useful resource to stash in your own tool box.
