Has anyone developed an open source version of Techmeme, Tailrank, Megite, OneSpot, Techfold

Is there anyone who has developed something similiar to any of these services? I really want to start a news site and tried looking for developers in job sites but nobody seems to have the skills to do it. Something using PHP, Linux, mySQL would be ideal. Send email to admin@whoila.com if you know of anything.
