Until yesterday, I used NewsMonster for my news-aggregation. I liked it, despite some caveats:
- couldn't change the settings, something interferring with my Firebird version
- needed Java for something
- ressource hog
- didn't keep old news (or even the links)
But all that didn't matter, I could aggregate recent news, cache(!) the underlying pages and had no great problem reading them.
Yesterday my life changed... I found FeedDemon.
Although it can't cache the underlying page and uses IE as backend browser, I like it far better. It is faster, smaller and keeps old news.
Sorry, mozilla-community, this victory goes to IE. (For now ;)
