Hello.
I love this site, and have used it for quite some time now.
Not too long ago, you added the advertisements of keywords being underlined on the site. I certainly understand that it helps pay for the site, but I wish something else could have been added instead. I have seen these advertisements before, and never found them to be too intrusive, except now you have to hit the X to close out the box :(. It is quite intrusive, especially if you scroll with the wheel.
Like I said, I completely understand the need to finance the site, I just hope you can find something less intrusive to replace that.
Just my .02.
