managing bookmarking for multiple identities?

I am mad for bookmarking, due to my fear of the crucial missing link being needed at some unknown time in the future.

I also have multiple blogs I need to bookmark for: this one, one about electronic voting, etc.
I want to keep the linkblogging for each of those sites completely separate, I don't want to mix everything together in one account.

So thus the problem: I think Furl is great, but I don't want to have to login for every single bookmark I make.  Ideally, I could have a set of bookmarklets: Furl this to Account 1, Furl this to Account 2 etc.
Maybe it is really easy to do this, in which case, please tell me.

In the meantime, the only way I have found is to use completely separate tools for the different accounts.  Right now I am playing around with BlogMarks.net, I can't say much since I've only bookmarked one page so far.  It is a bit slow as it completes because it does a screencap thumbnail of the page at the end, although you can skip that stage if you want.  I found a fairly useful comparison  between it and delicious: Testing BlogMarks.

The BlogMarks Blog has some neat stuff, like using GreaseMonkey to change Bloglines so that you can post directly to BlogMarks.

Any suggestions for managing bookmarking for multiple accounts (within a single Firefox profile)?

UPDATE: Currently I am managing it by using a different service for each account.
For linkblogging I like
Furl
BlogMarks.net
Linkroll

For just bookmarks with no attached comments I use the "traditional" delicious.

I tried Spurl but it just doesn't match the model of linkblogging that I like.  For a linkblog, I want to see the links plus comments/clip, but Spurl wants to have this elaborate category navigation with the comments hidden until the user shows them.  Spurl is a lot more about category than it is about just simple links tracked by date.  It also has this confusing thing with "category" AND "tags".  Some other sites do this also with "category" and "keywords".  Do we really need both of these?  I don't even know what the difference is between the two exactly.

I really like Blogmarks.net better than delicious. The interface is far superior.

I agree screenscaping process slows down the addition of a page in your favorites. I don't see it as a problem, though. When you visit a site, you can blogmark it, and do something while blogmark is processing the page.

Also, Blogmarks offers nice services, like the possibility to post your daily marks into your blog.

If you like blogmarks too, you may like this very simple firefox extension
