People are definitely spending bitcoins--BitPay Inc processed over 5.2 Million dollars worth of eCommerce in March 2013, and that was before the full media glut of April. Some excerpts from their blog:
This eCommerce activity from merchants selling computers, consumer
electronics, precious metals, and even government services has likely
eclipsed the illicit activity widely estimated from sites like Silk
BitPay has also approved over 1,300 new merchant applications during
the month of March, bringing their total number of approved merchants
to over 4,500. The explosive growth in BitPay’s business comes after
February’s payment processing volume of $687,000 in transactions with
2,300 completed invoices.
BitPay is even hiring right now, though for software engineers rather than sysadmins.
Similarly, Coinbase reported recently that they are processing 15 Million dollars per month. Their business is a combination of eCommerce and Exchange activity, though.
Talking more specifically about your desire to be paid in bitcoins, Finnish Company SC5 and the Internet Archive are both well known companies who have decided to give their employees the option to receive partial compensation in bitcoins; while Expensify supports Bitcoin as an option for employee reimbursement, focussing especially on the international use case.
Note the "partial" part of the above, however. Bitcoin is very good at certain things, but it's probably not very good at being your whole salary, at least not at present. Bitcoin thrives in being global, irreversible, and fast--not stable. I'm a huge Bitcoin fan, and I'd advise taking your salary at least partly in something else. It would suck to have a market fluctuation wipe out your ability to pay bills! It's better to hold and use amounts of Bitcoin you can afford to lose, seeing as how the technology is still early and experimental.
