If you blog regularly, post your pictures on Flickr, and use sites like Digg and Del.icio.us, pretty soon the information you are trying to gather together ends up spread over dozens of places. Suprglu is an attempt to "piece your web back together". Sign-up and you will be prompted to enter your user name at each site (not password) or feed URL. Suprglu creates a meta-blog collecting all your postings and bookmarks along with a tag cloud to help you navigate. For example, check out my amalgamation.
Suprglu just started and there are certainly a number of features missing. They definitely needs a search engine, and more templates options would be nice. Additionally, there can be a delay between the time I post here on Blogger and when the posts show-up on Suprglu. I wouldn't use Suprglu as a blog intended for an audience, but I will certainly refer to it in order to keep track of information I want to hold onto.
On a related note, there have been a lot of attempts recently to keep organize and link these useful sites. Check out diggdot.us and reddit.com. Trendalicio.us only keeps track of del.icio.us, but I update it regularly throughout the day to find tons of great links. Also, here is a useful library of tools for del.icio.us.
