Apps for techies
Facebook isn't exactly IT-friendly - you'll find countless applications for giving people virtual 'pokes' or rating their hotness factor, but not many that warm the hearts of IT pros. However, there are a few worth trying. At this point, they're not particularly popular, but given Facebook's growing presence in the business world, that may soon change.
Are you a pro in Python, MySQL, Ruby and PHP? Then let the world (and your boss and potential employers) know about it. Load this app, pick all the languages in the list in which you can program, and choose your expertise in each (from zero to five stars). It's great for impressing not only your boss, but potential employers as well.
If you're inside Facebook and don't want to have to launch a separate FTP client, try this FTP application. It offers exactly what you'd expect in an FTP client - copying, moving, deleting, downloading files and directories, and more.
It's a bit of a stretch to actually call this an application. Instead, it's a directory of developers and the skills they provide, so it provides an easy way to find someone if you need development work. And if you're advertising your own services, it's a way to try and get work.
At the moment, the pickings are slim, but they may increase in the future.
