I'm curious as to how my questions seem to get answered so quickly on Stack Overflow!
How do people watch for new questions on the Stack Exchange sites? Is there some sort of desktop widget which can automatically notify you on new questions?
There is an RSS feed, but mostly I just use the browser's refresh button.
You just go to the main page, find a question that interests you, answer it, go back to the main page (by now there will be new questions on the main page), repeat.
or you can follow tags, which have an RSS feed.
There is also filters, which allow you to aggregate multiple tags across multiple sites, so you have an overview of all and only the recent questions that are potentially interesting. However, I'm not sure how many people actually use this feature (I do).
