If you are looking for answers to programming questions on the web, you've probably run into Experts Exchange. It's a site with a lot of good answers to programming questions, but they're always trying to get you to register. And even worse, when you get to one of their answers pages, they make you think that you have to register to see the solutions to your question.

But you don't. The answer is right there at the bottom of the page. The people that run this site are really sly, they make it look like you must register. But if you scroll all the way to the bottom of the page (it'll be several pages long) the answer is there at the bottom.

Very shady practice. But once you know this trick Experts Exchange becomes a lot less annoying.
