I never have a problem either, but people are always complaining that the site is down on the FB page, while other people say it's fine for them. From what Q have said in reply it seems that the problem is probably at the user's end, and if the user reboots and clears cookies etc. they're usually ok. Nobody has ever been able to put their finger on what causes some to have problems and others not to, but there have been a lot of theories from geographic region, ISP, and - the most popular - the browser you use. Some people on FB swear that the minute they stop using Safari and change to Firefox (for example), all their problems cease. Then others immediately post that it doesn't work for them with Firefox, but Explorer is fine. I doubt they'll ever get to the bottom of it, but it would seem likely that if thousands are using the site very happily without any problems at exactly the same time that a few are saying it's not working for them at all, that the problem is some kind of incompatability on the user's part.
