Tshepang asked: A majority of the questions here would also be on-topic on Super User. What makes Unix SE different?
mattdm answered: @Tshepang I think the expert community is different. A lot of Linux users wouldn't describe themselves as "power users" at all — or even "computer enthusiasts".
mattdm expanded: @Tshepang Also, a little off the direct question, but in coming here from Server Fault, I've often noticed non-professional-admin Linux questions getting sent off to Super User basically to die. I think that's unfortunate, and I think we can be a better destination for those.
xenoterracide answered: SU was an old site, newer stack 2.0 sites have much more focus, in fact it could be accurately said that Unix SE was entirely covered by either SO, SF, or SU. However, as a site with sharper focus, we take precedence over those sites for Unix/Linux questions. (or at least we should, I've no idea on the SF policy)
Tshepang answered: It's a tough one. I personally felt alienated when I was on Super User. It was strange that my questions would be adequately answered on a site that also had a lotta Windows experts. I haven't used it much to really judge well, but many mentioned the poorer quality of the responses there (SU).
Michael Mrozek answered: @Tshepang I continue to think (and Ivo would stab me for this) that SU is too all-encompassing; it was creating before SE sites exist to cover pretty much all computer stuff that didn't fit on SO/SF. Now the SE sites have a lot of overlap, and we've been dealing with it pretty well; AU is a subset of UL, which is a subset of SU along with Apple and probably a couple others
phunehehe answered: @Tshepang I don't want to keep saying bad things about other sites and praise ours. I have been a frequent visitor on SU and I feel that things are so far apart. That is the key difference to me. In breaking the SE sites we have the advantage of fine-grained interest. So, when a *nix user visit UL he/she will always see familiar topics that are interesting to him/her. There can be quite some overlap between SU and UL, but in such cases I'd always prefer the post to be on UL if it is on topic.
