i checked out the website, and it's ok, not bad, though it's not completed yet, let your friend check out
www.jidaw.com, i'm sure he would get a few ideas as per content.
i dont think u need a horde of writers to sustain a website, as new members register with your website, you could suggest a topic and ask interested members to send a write up which would be published on the site.
Anyway, i think the bottom line is to advertise, advertise and advertise! set up a link from nairaland to your website ( if seun would allow that), set up links from your websites to popular tech websites, with time you would generate traffic to your site, and then content would not really be a problem, cos you would even get unsolicited articles from interested people.
Anyway, keep in there, dont give up even if starting up is a bit rough, do you know that statistics show 90% of new businesses fold up before the first five years of operations? cos the enterpreneurs were discouraged by obstacles? anyway, me tinks i've yakked ( talking endlessly) enough.

All da best
