along the lines of same same but different is Netvibes, a “custom made web 2.0 home page solution” that i stumbled upon while bloglining (it was being used as an event planning aggregator — good idea!)
similar to SuprGlu, it aggregates your feeds in one convenient place, but different in that (1) it is private (2) it updates in realtime and (3) you can incorporate e-mail accounts, to-do lists, websearching and webnotes alongside RSS and ATOM feeds to blogs, flickr, del.icio.us, CiteULike, and a myriad of other sources. it also supports OPML files.
i especially like the built-in podcast player!

(okay, more different and less same same than SuprGlu)
SuprGlu is a relatively new app that aggregates feeds from many social softwares such as del.icio.us, flickr, 43 Things, MySpace, Digg, Last.fm, and more. You can also add RSS or ATOM feeds from blogs.
SuprGlu is about bringing the pieces of your web content together into one central place for you. — SuprGlu
it’s like having an überblog that blogs all your latest bookmarks, photos, goals, books, music, and so on, all in one place.
these days i use quite a few social apps to organize my life.
see how kothari.ca miscellanea sticks together with SuprGlu…
i like the SuprTags feature, that brings together “twenty most popular tags displayed with varying scale based on usage across your sources.” but it would be even kewler if SuprTags listed ALL my tags from across flickr, del.icio.us, LibraryThing, 43 Things, and kothari.ca allowing for federated tag searching!
LibraryThing now has a librarian (thingamabrarian!) amongst its stacks, who will be “generally helping raise the library-science quotient of LibraryThing.”
have i said how much i love my LibraryThing?
