What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

I think it would be awesome if there was a feature which took into account your activity on the site... and did a search to find (as if by magic) questions you could answer.

(Apologies if this is already suggested, It seems so obvious, but I can't find it.)

Criteria for the algorithm may include:

  • lack of existing answer
  • number of answers you've given on similarly tagged questions.
  • number of questions you've asked on similarly tagged questions.
  • number of upvotes you've received on similarly tagged questions.
  • (all of the above but replace 'similarly tagged' with some kind of keyword matching algorithm.)

Perhaps there's even a real fancy neural network or something you can do this with so you don't have to work out the weightings.

Also, add notification so you can get in quick and answer :-)

This already exists... in a way. If you fill in some Interesting and Ignored tags (in the right sidebar), the home page of the site shows primarily questions in those tags that you're interested in and is weighted towards unanswered questions.

See the blog post Stack Overflow Homepage Changes for details on how it tries to figure out which questions are most relevant to each user.

There's currently some work going on to improve the homepage sort order; it provides a lot of information about the question and about your interesting/ignored tags, so you might want to try fiddling with that to see if you can come up with an algorithm that works well
