Archiving old blog posts - yea or nay?

[JamesDziezynski]

I'm building up my personal website. When I moved from my old domain to my current one a few years ago, I  had moved a folder with all my old blog posts (from an old blogger.com account) to an archives called /blog/. It's bad enough the entries just text and nearly all the images aren't there but because of the way I moved over the posts, I have 200+ duplicate page titles with no meta descriptions.

Is it worth saving these posts ? (putting them into an archives.mysite.com sub-domain?) I already have the folder disallowed in my robotos.txt file and there's nothing really incredible content-wise in the archives, though they are some of the oldest pages on my current (3 years old) domain. There's no real SEO thought in them as this was just a fun personal blog at the time.

Thoughts?

I have a blog that gets lots of posts that are of temporary value.  We delete a couple thousand posts each year, but before we do that we run analytics to determine which ones are pulling significant traffic from search engines or from links on other websites.  When we find these we create improved and current content on a new URL and do a 301 redirect to the new page.  All other pages are 301 redirected to the homepage of the blog.

Not too much traffic, not many viable incoming links. They are just for fun -- I'll probably nix them.

Do these pages receive any traffic?  Do these pages have any links from other websites?

If either of the above are true then they might have some value.
