I just spent an hour looking for an .asp script to parse an internal RSS feed from my site and display it on the homepage. (I'd be happy to use one of the many php scripts available, but my site is not hosted on an Apache server). I wasn't having much luck with the asp scripts I found - they all seem relatively complex to set up and I'm not much of a programmer.
I don't know how long this service has been going - I certainly wasn't aware of it before - but I've just tried it out on the front page of my site and it works wonderfully. It's exactly what I've been looking for, for about three months.
I have zero affiliation with this service, but I'm so delighted with how it works, you'll have to excuse me my out-of-character evangelising about it.
However, if you're using .asp, sticky me and I can give you the rss/asp code to use--it's really pretty simple, and you can control it through a .xslt file. It works well for me on my .asp pages.
