Hello, I have a high traffic site and don't want to install wordpress on my server since it will slow down everything. So I'm thinking I can get a free wordpress domain, something like: mysite.wordpress.com and DNS mask my URL: blog.mydomain.com to this free wordpress domain. Is this possible? If so, what are the pros and cons? Will my domain still get search engine "juice" from links I get to the blog, etc? Will my site be penalized for "cloaking", etc?
