I am not sure how much these kinds of tags are helping:
Is their use encouraged on Stack Overflow?

This question appears to be off-topic. The users who voted to close gave this specific reason:
They are meta tags and should be discouraged with extreme prejudice.
If you have retag or edit rights remove them - but be careful. I checked simple and there are some on the first page that should be something like [simple-loop] (though seeing it written down I'm not so sure), so a straight delete isn't always appropriate.
Bringing them to the attention of the wider community is a good thing.
