Today, I've got plenty of Android/Java questions on the front page, but also some that I just don't understand. For instance, this one, and this. One is tagged with dynamics-crmdynamics-crm-2011, the other with asp.net-mvc-4. I've never used these tags, so what makes them appear?
I know about the Tag Future Report, but mine doesn't show anything related. I even browsed my profile's tag listing, but it turns out I've never asked or answered a single question for any of the three.
So my question is, why are they there? I don't browse ASP-related tags, and I don't use Dynamics CRM at all, so no action there either. It can't be based on being a "popular" question, because they both have zero votes and low views (at this time).
The questions aren't even topically related to my main tags as far as I can tell. Is there some sort of question scanning algorithm that lumps things together even with differing tags?
