Huh, fickle crowd. Hate is such a strong word!
When I used Dropbox, I tend to just get the link and send people that. I don't screw around with sharing folders with other users or any of that, and I don't keep anything local on my computer. Those options are nice, but unneeded for simple file sharing.
And the bonus, as was mentioned, is that the link will last; it doesn't expire. You can also see download counts, which in some cases is useful. On another hand, the synching folders thing can be really useful, as long as people know what they're doing, and you have the admin settings setup however you need them.
One of the others mentioned...can't remember if it's Hightail or WeTransfer, seems to have a spotty data transfer rate sometimes, and the files disappear after awhile.
