If you use Bloglines, it’s time to move to another RSS reader services/tools. Bloglines will be closed on October 1, 2010. More details about this can be found in a blog post. A little bit background, Bloglines is a web-based RSS reader. It was pretty popular few years ago, and Ask Jeeves acquired this service back in 2005.
If you visit Bloglines homepage, you should see a notification about the closing and also some guides on how to migrate your RSS subscriptions to other service. I have migrated my subscriptions to Google Reader long time ago. Just in case you need to backup your subscription, you can do it now.
