This is a very sad news...... I know I can find other services, but I added this to my mom and dad's computers, and they do have now all their bookmarks + passwords saved.
No, they don't even know that (Xmarks) is running, and I don't even know how to tell then "hey, you should pledge 10 € here..."
That made me think: how many moms and dads are using this service??
Better yet - offer the service free-to-use with some trivially low amount of space (like 5MB) and then charge per year on amount of space ($10/yr = 50MB, etc).
