Softwaretopic.informer.com is obnoxious. It arbitrarily combines words so it insinuate itself into Google searches. Search for "personal wiki" and you get a page for "myob plus wiki" from this "service," for instance. Should you click on the page you get all kinds of things for "wiki" and a program called "MYOB Accounting Plus." Every day there are more inane and annoying combinations like that. I try not to fall for this ploy, but I do at least once a day.
I blocked the site in Google's search settings, but it seems to make little difference. It's nothing but "Search Spam" and it should be penalized by Google, not receive a high score in searches.
