I am interested in answering questions regarding C, C++, Linux, networking, etc. I know that to increase in reputation the fastest way, it's very necessary to be the first at replying to the question. How can I be alerted in the fastest way?
You can also set up an RSS feed for your favourite tags: see "Searching and RSS" in the FAQ.
I had a little auto-update webservice for a while until I got my servers IP banned... ;)
(Side note: would such a service that fetches new questions on favourite tags be a good or a bad thing? It would mean a lot of requests to the SO server, but a lot more request against my server, as long as there are at least two users connected)
