I used to use Firefox’s Live Bookmarks. It was a great way to read RSS feeds, or it was until my feed collection got too big. Now I use MyNT, which works in a similar manner. When you read feeds in MyNT, you middle-click items to open the post in a new tab (like using Live Bookmarks). That’s how I read my RSS feeds.
There are masses of RSS-users who like to read entire blog posts in their reader, though some like summaries better.
So… What group are you in? Are you a full-feed-fanatic, a Live Bookmarks/MyNT maniac, or do you prefer summaries?
