I'm inclined to agree that sometimes it can all be a bit much. But I also don't care - I've got a lot of personal enjoyment and utility out of posting links to del.icio.us, and it seems like a lot of other people get value from reading them - either directly, or on aggregate.
I've been trying out Tumblr recently and I'm thrilled that it's allowing me to do the same thing but with images and videos, and the occasional quote. It's a very free and easy way to keep track of things I think are noteworthy. It turns out I don't want to find most of these things again, so the lack of tags and other things is fine - a blessing, even.

When life gives you lemons, suck 'em, honestly, lemons taste awesome. When the web gives you croutons - feast!
