Has google changed the world of blogging?

[Wehner Smi]

I having been see new reports on that google is hitting sites with to many blog post. Are other bloggers starting to delete some of there blogs? They are saying that google is starting to reward site with less blog post.

Deleting non performing old post is a very old strategy. Its not something new. It can help but like everything else there are no guarantees.
If google deems most of blog post as spam or "low value content", it will not matter if old post are deleted or not.
