I lost all bookmarks as well (in Google Chrome Canary, not stable Chrome) due a bug. Canary sometimes is buggy and parts of the theme (e.g. scrollbar) sometimes even look like OSX, probably because most Chrome devs work on OSX and don't regression test the Win7+ daily-build that often. Storing bookmarks as *.lnk as with IE3+ is still the way to go. Though, I found out that 50% of my bookmarks are obsolete and many were never archived in archive.org due evil robots.txt entries.
