A problem that I recent have had (and, by looking at their profiles, many of my friends) is that when you enter an employer on your profile, it sometimes links to one of the new Community Pages instead of their official page. This is relatively easy to fix, if you are willing to use Firefox.
Now, I don't use Firefox very often because of its bloatedness, but there are a few toolbars and addons that I like to use every now and then. One of them is the Web Developer addon.
