The reality is, that Twitter could have easily and simply fixed this issue long, long ago. But, to do so they would have to place some power in the hands of the users. They don't want to do this because it means a loss of their control over what you see. We already know that FB experimented with pushing people's mood and views on subjects around; Twitter is not immune to such temptation also. Simply: assign 2 scores to every user, each out of say, 1000 (100 is not enough given Twitter's large userbase). 1 score is a category score, such as "lgbt politics" or even finer-grained than that, easily done by simply reading all of a user's tweets and using Bayesian (or some other classifier) auto-classification. This is a measure of how the user is perceived by others, inside that category. The other score is a combination of per-region or per-country (because in general, people care about the people in their own country or region more), plus number of times a user gets a like or retweet in that same region, etc. Then, simply let people filter based on those 2 scores. If I set score 1 at (cutoff everyone below 900) I will get top tweeters in each subject; if I set score 2 at (cutoff 200) I will let most tweets across the world reach me. etc. etc.
