Do RSS feeds have "just" text that you pull to get the article content, or are you parsing the webpage somehow? If so, how?
I've done something slightly (well, about 1% :-) similar for the "Popular" page on pinboard[0]. It used to have a line or two from the start of the article, using a webpage content extractor that got turned off, so I can't use it anymore.
One arguably nice thing about mine is that it's updated once a day, and it remembers what you've read yesterday, so new articles are marked, and you can flip a switch to see the new stuff first.
Thanks!
