Are they still spawning?

Congratulations!

It took mine almost 2 years before they started spawning, now it's like clockwork.

I had the same question. Sounds kind of nasty. Here's wiki's explaination.
A blog (a contraction of the term "weblog")[1] is a type of website, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.
