TL;DR; Question is deprecated.
The default SO algorithm, made finding the right questions to answer very difficult as questions were all over the place, different tags, many topics.
The question was how to curate the SO feed to our personal tastes and interests, with filters like "minimum reputation of the user who asks"... or "tags that are not of my interest at all"... so that we can weed out topics were not expert in, or we have no interest in.
SO made improvement to heuristics, and it also provides now two useful tag based filtering mechanisms:
- Whitelist tags.
- Ignored tags.
Therefore, question is deprecated.
