It has happened a number of times that I need to subscribe to an Internet forum in my RSS reader, just to find out that the forum in question doesn't support RSS, or that its support is just not good enough.
Since a lot of fora introduced image authentication for running a search I more or less by default head straight for a Google Web Search now. By using the "site:" argument it is easy to limit the search results to one specific forum. The world would be a better place for a geek like me if web search would offer an RSS feed to enable easy monitoring of new results. But, Google only offers feeds for their blog search and not their normal search.
But! I just found out that rival search engine Microsoft Live Search is offering a splendid feed for all search results and I really like their polished interface as well. This is the first time I am actually impressed with Live Search. Nice work, Microsoft! I'm sure I'll be using Live Search from time to time in the future.
