Projects in the topic search

The problem I typically find very hard to figure out in the whole SUSE company who is the go-to guy for a certain skill/knowledge/experience. I'd like to have some place where one, who does not know people around him, can just browse and search for people by some tag or label. Sometimes you have a problem in a specific area but you don't know who to ask to, or even if you do, you don't know there were many other people with the same knowledge/experience you could have ask before.
