I think it’s great. If you have had your portfolio online already you may also start selling your photos to magazines, there several thousands in US alone. If you're keen and you don't mind sitting at the computer all day you can find all of those magazines in the Internet. Also, there are quite a few really good books and websites out there if you go looking. My suggestion is to check one of them – http://www.freelance-market.net – and try a couple magazines until you find out what does the job right for you. Of course there are others, the good sites will give you all the information you need to start that includes links, description, payments, etc... without the information overload.
