It looks like Nature Publishing Group is doing a good job overall of embracing the web lately, particularly with its new free job posting service. Naturejobs.com announced its free "science recruitment" service in late November, mentioning twice in the same press release that Naturejobs currently receives 1.5 million page impressions and 200,000 unique visitors every month. (For comparison, Gawker.com, the Manhattan media and celebrity blog, receives 1.5 million page impressions per week.) I'm not sure how useful this new free service will be to employers or job seekers. As Craigslist has found, free job classified services result in a lot of junk job ads being posted, which clutters the space and makes it difficult for visitors to find good jobs. (Think about it, if the employer is too cheap to pay $50 or more for a job ad, how much are they going to pay you!) Craigslist job postings are free in most cities, but Craig Newmark and company found that charging a modest fee of $25 in NYC to $75 in San Francisco cut down on clutter and headaches and made the experience better for everyone. Naturejobs is taking the middle ground of offering both free job listings and paid listings that receive more prominent placement on the website. Of course, it doesn't hurt to try the free-for-all method. Naturejobs.com clearly is looking to grow its site traffic, so a flood of job postings, visitors, and ultimately advertisers, would be a nice problem to have.
