Okay, let me show you a screen shot first:-
I would like to call these 'Filters' available for me to search for questions without typing anything in the search box manually. But seriously I would like to take a look at questions that have my 'Favorite' tags. Now you might say that we have this :-
But then there I can click one tag alone and results are viewed only for that single tag. Now what I feel is we want is a filter called 'Favorite tags'(which should be available in the bar shown in my first screen shot). If I click that it should show me what will be shown by this URL(which includes all the favorite tags listed in the second screen shot):-
Making it generic :-
Wouldn't this make it easy for me to get to the questions I can best answer? Wouldn't it also save me time that I could use to make better answers? (You might say 'Just type in the search term!'. But thats fine if a user has just 5 favorite tags as shown above. What about like 10 or 15 tags!)
Think about it. Post your opinion.
