I think that this site has improved greatly in recent years.

A while back, some one dropped a nasty virus on me using this site, and continued doing so when I went elsewhere (since I couldn't gain access to Xmarks).

Things went fine for a while, but when I started encountering problems, I reported it, the mods in "the other place" went into immediate denial and refused to believe they had a problem. I got my local geek to look into it, who confirmed that somebody had hijacked the mods' access "over there" (essentially the hacker was posing as a mod), upgraded my security and fixed the problems that had disabled my access.

Xmarks has worked perfectly ever since, other than some incompatibility issue with posting photos (no idea why I can't).

Yes, I feel safe here, but now I am very aware that there are malicious people out in cyberspace who have far too much technical knowledge, and far too much time on their hands.
