-The cliff's notes view that Diigo has which saves time going to a site because you can have several sites and click expand on them.
Yes, that's about the only thing I can't duplicate in Firefox right now, and that's why I said I hope it could be integrated with Firefox's bookmark system, in a way that I can look up a bookmark and see the highlighted parts in a submenu.
What I currently do is when I highlight something with Wired-Marker, I also bookmark the page and tag it with "wmark" (along with other tags). So at least now I could easily locate bookmarked pages with highlights, which is more than what diigo gave me (the "Annotated" tab often gave me nothing or no more than 3 bookmarks, while in fact I had a few dozen).
-The problem with having to deal with two different exports on two different locations.
This is easier to deal with. I've separate system and data partitions, and Firefox profile is on the data partition, which is backed up regularly. I also set Scrapbook, Zotero and Wired-Marker data folders away from the Firefox profile folder, into places where they're backed up more often than the FF profile folder tree, and made available for my search tool (Archivarius). (Though Archivarius doesn't search Wired-Marker or other sqlite db yet.)
Also since Wired Marker is Firefox only, it really leaves me chained to that browser and sometimes when Firefox is slow for me I switch to another browser and just use the Diigolet. I wonder if the Foxmarks people would be willing to add Scrapbook and Wired Marker syncing to their features if someone suggested it... a black hole is still better than no hole.
That's a good point. Though Firefox 3 is really fast on my desktop and I use it almost exclusively now, I really don't want to be tied to a particular product, either. For material related to my research, I always try to save the page locally first. (I set up proxomitron filters to help me get material on my favorite sources into shape.) But Firefox bookmarks, Scrapbook and Zotero all can export their databases, and Wired-Marker uses sqlite, a standard format. So I'm not too worried.
Still, I'm on the hunt for a better solution, as you do. If you stick to diigo, please let me know if they get improvements.
BTW, what good does it do if Foxmarks can sync Scrapbook and Wired-Marker databases? Can you use Foxmarks in browsers other than Firefox? If it's not cross-browser support but cross-computer support you're after, than there're other tools that let you sync the entire Firefox profile, I believe.
... a black hole is basically an account with bookmarks with so many different tags and so many bookmarks that you end up not being able to check back on any of them unless you want a specific one ...
Another good point, that's why I started moving my bookmarks to diigo in the first place; my firefox bookmarks were getting out of hand, and there were no tools to mass-tag them according to the folder structured then (there are now). Too bad that didn't work out for me.
Now with some good extensions, my black hole is getting in order. Tagsifter
is my favorite; it allows me to filter bookmarks with something like
"tag1 - (tag2 + !tag3)"
Not possible with diigo or any other social bookmarking sites.
I also like FF3's smart bookmarks system. Though it's not very user friendly yet (some geeky tuning involved), it allows me to add dynamic folders to my bookmark toolbar. Diigo has lists, but lists are static, and it doesn't have tag bundles like delicious.
It's also easy to delete a tag from multiple bookmarks at once in Firefox -- another thing not possible with diigo.
So, on balance I like Firefox's bookmarking system (with extensions) better, and judging from what happened this summer, the speed of improvement clearly favors Firefox community as well. Diigo does keep moving, but the pace is slow.
