I am not sure why you'd want to do that, you'd miss out on a lot of things you didn't know you knew the answer too, I'd think. Besides, there are lots of alternatives:
Favorites can be bookmarked or highlighted
The home page lists your favorite tags on the right:
As you can see you can add new tags to that list with the textbox underneath it. Clicking on these will take you straight to their question overviews and each is just the base url
http://stackoverflow/questions/tagged/ plus the tag name. You could bookmark those for easy access.
Moreover, any question that matches your favorite tags are already highlighted on the home page:
You can create your own homepage with all your favorite tags
A lesser known trick is that you can combine tags to show only questions that match any of those by using the
questions/tagged/ URL with the word
or inserted between tags:
and you can string all your tags together; now you are presented with the list of questions that match either the python or jquery tags:
and you could bookmark that one too. If you feel uncomfortable creating such a URL by hand, just enter your tags with the
[or] tag in between in the search box and hit enter; e.g.
[python] [or] [jquery] [or] [mysql].
You can filter questions on StackExchange.com
Last but not least, you could use the Filtered Questions feature of stackexchange.com:
Here you can filter questions from across all SE sites; here they are filtered on my favorite tags. The selected filter sticks so next time I visit that page it'll still show me my filter of choice. Bookmark that one and you get to see all relevant questions in one place!
