The linked word ads can be blocked. I wouldn't mind if they were consistent and actually made sense. I just did a quick random check, and the words "Communications" and "access" link to signing up for BT services. British Telecom, on a site in America, visited largely by Americans, in articles discussing Communications Streaming Architecture and the PCI Express architecture.
I can't believe those are worth having on the site. Who's clicking those links? All they do is make the text look messy because now we have orange links (at least they're not underlined and bold or whatever it was at first as I recall), and they don't help the reader in any way, not even offering something they might be interested in. They're just completely random dictionary links.
At least there aren't too many of them. Of course, that makes them even less lucrative, if we only see one per article.
