That means it's a bit of a stretch for the company to describe its 'Fast 50' list of job categories for which demand risen or fallen the most as "the leading gauge of online hiring trends". However, the fact that the list is generated from more than 100,000 jobs means it is of some interest.
Top of the list is HTML5, which rose by 34% from 1Q11 to 2Q11, while general HTML jobs only rose by 7%. Not surprisingly, the growth in interest in HTML5 was accompanied by a 10% drop in Flash projects.
Other development specialties falling include BlackBerry (down 6%), Windows CE (down 42%, but that's hardly surprising), Windows Mobile (down 16%, ditto), Windows Desktop (down 30%), .NET (down 7%), Visual Basic (down 11%), and C (down 13%).
Rapidly growing technical categories apart from HTML5 include Google Adsense (up 27%) and Android (up 20%). On present trends, Freelancer.com predicts Android projects may outstrip iPhone by the end of 2012, as iPhone demand rose by 9% in the second quarter.
