Are Exact Match Domains on Blogspot or Typepad Effective?

[ProjectLabs]

It is well known that exact match domains are quite effective right now for ranking for a specific keyword phrase. Does this work equally well for Blogspot or Typepad exact match subdomains? For example http://seattledentist.blogspot.com

Google may reduce the value for domain with keywords in near future.

Watch the following Matt Cutts video:

If domains are available for your desired keywords, you may go for it. I wouldn't recommend to change keywords as well as additional investment.

Exact match on subdomains have very very low weight.  Anyone can create thousands of exact match subdomains without much effort and cost - in fact the exact match weight has been on the decline even on the root domain.
