humans tend to love lists of things that give ranking of things. So its going to get people clicking on it. But the actual lists don't really tell you anything. At best these kinds of things are more interesting when they track trends year in year out comparing its own data. But even that isn't terribly useful unless theres some big shifts. Certainly announcing the things on the list as "winners" is silly, all this is is a marketing effort for stackshare, which is fine, but its just not terribly useful.

Obviously pure speculation:

Maybe several people on this list conspired to create an article listing their products and then all came here and upvoted the article?

There's a lot of value in getting onto the front page of HN.
