…I ain’t paying $12 for a domain name renewal (well, renewal + whois privacy)…especially for my ‘hobby’ site ie. this site.
So after 3 years using vortex69.net – although I only have the blog since ~6 months ago – I’m moving it to vortex69.tk .
The 25 visits in 90 days will be biggest enemy now. 
For future reference (for myself, or anyone who finds this), this is the code to mass replace a string in mysql:
UPDATE table_name SET column_name = REPLACE(column_name,’original_string’,’replace_string’)
on wordpress, updating the posts would be:
UPDATE `wp_posts` SET `post_content` = REPLACE(`post_content`,’old domain’,’new domain’)
