As always, the implementation here, the lines of code in index.php, doesn't really matter. Anyone can code a job board given enough time. The questions that matter are rather how he got his audience to come to it:

- How did he make his offering known to potential clients? - Why did the clients choose his page, over the N many competitors out there? What's different or better about it? - Conversely, how does he get his job-seekers? Are they of particular quality?

The index.php file is old news. The getting employers and candidates together in a nice package is the valuable part.

(I'd actually be looking forward to hearing about the making of this job market.)
