Daily Tabs
When Mozilla implemented tabbed browsing, I created a folder containing 20 links of sites that visited every day. Serveral times a day I would open this group of tabs and get updated from all my favorite news sites and blogs.
With the implemetation of RSS, I find that I rely on that more on RSS than the daily tabs. There are only a few websites that I actually need to see. Most have a lot of graphics or photos.
Because of this, I've redone my daily tabs:
-Urban Pug
-The Unofficial Apple Weblog
-Jacksonville Weather Daily Details
-Flickr: Photos from your Contacts
-UserFriendly Strip Comments
-MacCast
-PodcastAlley.com
-del.icio.us/popular
-FlickrBlog
-MAKE: Blog
-Google Sightseeing
