Codecademy did a good job though and http://www.theodinproject.com/ too.
EDIT: Also, the job prospects did not look too good because of the fierce competition. What motivated me was doing my own apps/sites (lego for grown-ups), or at least work on a startup, but the required resumes were really daunting. Sysadmin just didn't have the rockstar flavour to it (I think it's a fine job, just trying to convey the fact that a certain air of adventure needed to be present to lure me to stick with it- i.e. the same reason 13 year olds learn the electric guitar).
