I've ended up searching out the mobile versions for most of my news sources and that seems to work. In some cases, it's their rss feeds. For example, for the NY Times
http://www.nytimes.com/services/xml/rss/nyt/Space.xml
But you may need to set up cookies in iSilo for logging in and should double-check where the RSS takes you as it might only be headlines without extra links or easy ones to get the articles.
I also still use Avantgo in spite of it being a memory hog and the older versions not being able to use the memory card.
