You recently deleted a post as "only asking about how the patent system works in general". How the US patent system works is exactly one of our two on-topic subjects. You also thought the questioner was making a thinly veiled slam at a web site. A careful reading of the post would have shown that the poster had trouble formulating the question but that the site name he used was intended to be fictitious and that his question, while very basic, was on topic if not well expressed.
If a question in meta is not the proper way for me to point this out please let me know what the proper way is. Obviously I could not comment on or flag the deleted post.
