Ars technica only provides a blurb trough rss and iirc no topic filtered rss, hardly a good or usable solution if one has to get out and find content outside the reader
Subscribers get full text and they offer per-section feeds.
Beyond that, a full-featured client can implement either of those features. I use Newsblur.com which allows you to control whether you see the feed's description or the readability-filtered page, and you have a training system to up/down flag authors, tags, and arbitrary text.
