Bloglines turned 1 not too long ago and crikey(!) did they add a some cool new features to the plain old feed aggregator. The new look is also a refreshing change (though the old utilitarian look suited me just fine too).
The Clip Blog feature is perhaps the very coolest. It's a convenient way to save "clippings" from blogs or sites you read in Bloglines.
Bloglines explains what Clip Blogs are for:
When you see something you want to save or share in your feeds, just one click posts it to your Bloglines Clip Blog.
I have mine setup right here to play around with. The unfortunate thing is that there is no RSS feed to it (there is a "Subscribe" link, but it seems to be in a Bloglines-specific format). It works fine within Bloglines though, and that's the whole idea I guess.
And finally, I can get Bloglines to sort my feeds. I have a whole lot of them (on the right sidebar) and they were sorted by the date I added them. Not the best arrangement but it's grown so big I just couldn't get down to organizing them into folders. Well, at least alphabetical sorting is slightly better. I'm not sure if this is new, but I noticed I can now check a box next to each feed and move them into folders.
Bloglines made Time Magazine's list of 50 coolest websites and it deserves to be there. If you use a RSS reader or feed aggregator of some sort, and are disatisfied with it in some way, give Bloglines a go.
