What bibliography software do you use to save online article refs?

I don't have a useful suggestion for you - I'm still a manual citation and bibliography keeper for some reason. I flirted with endnote for a while, but it just didn't take, and every time I look into other ones I am confronted by the same discouraging feeling - that it's somehow "too late" and I'd have to spend more time than it's worth not only learning a new interface, but actually tediously filling in any program's inborn bibliographical database component-by-component with all the stuff that I already have laid out happily in existing reference lists.

However, I am now (again) seriously considering making the transition, because I guess I've admitted to myself that it will only get harder to switch the longer I wait, and ultimately it is silly not be using something made for this (especially for online research). In particular, I've been looking at Zotero... You say you've used it Brian, I'd be very curious to hear what you think, and whether you've now tried any of the other options you mention since you posted this?
