Say what you want about underpaid IT jobs, they're gateways to often very lucrative niche markets. Getting exposure to enterprise applications and system frameworks is invaluable. I work in systems development, started at 16 working as an apprentice administrator in HR working for their systems team earning £6,000 a year and now I'm 23 earning £50k a year in an industry where you can quite easily snap up 6-12-18 month contract work for £500-1k a day if you wanted to make the switch.
There's a lot of technically minded people out there cramming themselves into first line support because they feel it best suits their skill set, when in fact if they took the risk and explored new technical territory they'd realise it's just as straight forward and full of development opportunities.
Now it just seems like I posted that job

to provide counter-balance, yes it does seem very underpaid. But I'd do it over working at Tesco or wearing a sign any day of the week, and there's a lot of us techys doing that!
