Absolutly!, all depends on how you do it. It's not just about finding a need to fill anymore, you need to do the right research to see if there others doing the same and how many others are doing it. Try to get into something easy to sell, low investment, and something that you can understand or can learn to understand it. eBooks, just are good and they're still hot, but can you wright. If so, how fast... Hey, but if you know a lot about something, well ebooks or podcasting can be for you...

Learn a little about Internet marketing, find good Internet advertising companies, and see what can work for the type of business you decide to go for. Let me tell you some of the stuff that are hot rigth now:

Storage (computer servers)
Internet Security (anti-viruses, spywares, intruter detection)
Home Automation (security, survilance)
VoIP or Internet Phone services

I hope I help a little...
