Found a new-to-you blog that you want to read, but you don't want to get sucked into it for the next few hours? RSS Replay looks like the tool for you. Give it an RSS feed and how often you want it to give you a new post, and it will do the rest. You can specify a new item from the backfile every day, every few days, or other intervals. You can also set a PageRank filter so you only see posts that have PageRanks above a specific threshold (all, good, great, or best).

This brings "slow reading" to a much different level!
