Blogger Blog with a PR1 Rating - what is it good for?

I've been busy setting up new pages, and working with CPA and ignored the blog that I have been running for 4 years. I just checked and it has a PR 1 rating. Besides using it to link my other pages on the Blogroll is there anything else I can use it for. It gets little traffic, but has over 260 unique content posts. The other drawback is that's it's on blogger - I didn't know better at the time. Any suggestion wold be great.

if you have scrapebox...blast something
i mean is 4 years old and i don't think it is any worry
keep building links because you will get some clicks from time to time
