The growth of Twitter (and the hype) continues. Facebook is threatened. Google is threatened. And yes, job boards are threatened. Right?

Millions of people are turning to Twitter (and Ning, Facebook, LinkedIn, and others) to find out information about jobs, companies, and other tidbits of data previously the domain of job boards. Recruiters are twittering madly, looking for the elusive top-flight passive candidate. There’s enough buzz that even the most recalcitrant of HR managers have at least gotten curious enough to look. There are even a few Twitter-based job sites. (Yes, I’ve visited them. No, they’re not that great…yet).

But I think reports of the death of the job board are perhaps premature. Twitter is a broadcast tool – which can be very powerful in pointing people to content. Job boards are content – searchable, focused content. The very brevity that makes Twitter attractive also limits its value as a content source.

What makes a good (and I emphasize good) job board work for both employers and job seekers is functionality and focus. If you need beer brewers and ‘BeerBrewingJobCenter.com’ has 500 daily visitors and 10,000 qualified, vetted resumes, why would you waste time Twittering (or, for that matter, spending your hard-earned bucks on Monster)? The site has done the work for you. It’s old, boring technology – but it works. Same story for job seekers. I can Twitter and build up my beer brewing followers (and hope they’re paying attention when I twitter) – or I can go to the job site and find some work. Most likely I’ll do both.

Tools have been (and continue to be) built that attempt to harness Twitter and make it more useful. But until it proves its efficiency as a recruitment tool, I suspect it will remain the domain of that certain subset of recruiters who love technology and have more time than money. However, it may well become a job board owner’s best friend – a great one-on-one marketing tool.

What do you think?
