To implement an online rss reader just like www.bloglines.com is not difficult.Every registered user will add their feeds to their customed online rss reader.However,if any user have sent their request of reading rss to the server,the server will not return until the content of the feed is fetched and then return back.During this process,the ruby process is blocked until the feeds is fetched, if lots of users want to do that,will it cause a block? Since each fcgi or mongrel instance means one ruby process and ruby does not provide a local thread.

I would use BackgroundRB to load the feeds, parse them, and place them in a database. The client can then poll periodically for the update. Michael
