every blog has there own feed link build in - when you subscribe you get the latest posts to date. however if you really like the backdated posts, is there a way to modify the feed link to get posts from a specific date (e.g get posts from 2008 to present ) so that then can sit in you rss application giving you the ability to tag then and read them when you get the time

this is something that i have not been able to fine through google, so im not sure if what im asking is possible

thanks
