Not even really sure what this one is, except maybe advertisement for free books?

MAA Number a Day

Daily blogs are fun and interesting, but very difficult to keep up with forever.
This blog posted a daily number review with lots of interesting math facts behind each number for several years.

SPANISH FORK CLASS OF 2004

Some blogs are merely placeholders, or areas to gather people together in a space on the internet.

Looks like this blog was a gathering place to get alumni from a specific high school all to share info with each other.
There are eleven other blogs of the same ilk, all set up for their individual graduation year.

Odds are these people all found each other, then ended up on facebook or somewhere else and left the blog in the empty internet space.

SemioPhenomenon

Sometimes there is such a thing as having too many blogs.
Not because you don't have something important to say, just because there's only so much time in the day to keep a blog updated.

This particular author has 5 other blogs that are up to date, but this one unfortunately fell off.

Astrona - Space & Astronomical Art Journal

When I'm looking for an orphaned blog, I have to say that for every orphaned one I find, there are 10 to 100 that are alive and running.

Searching in the sci-fi genre there are piles and piles of geeks still going strong with blogs.

Some of the orphaned blogs you find out there are really put together and it's clear someone spent a lot of time on them, but then let them go unused for over 2 years.

History of Graphic Design~Jackie Sanch

From Endless Summers to New York City.

Some bloggers take years before they start to fade away, while others simply disappear abruptly after a few months.
This blog was a nice look at some different graphic designs.
The author posted about once a week for four months, then stopped and hasn't returned in 5 years.
Really makes you wonder, did something happen to the person, did they simply decide to stop posting or did they just forget?
