With the advent of Ruby on Rails and other web frameworks, not to mention the constant growth of the internet as a whole, there’s been a definite increase in web applications in just about every niche.

In some niches there’s saturation, so this begs the question, is there any money to be made investing in web applications.

Personally I think there is, a lot depends on the niche or vertical the application is in, how well it was made for the users, and how well it’s been marketed.

End of the day, the same old principle applies for any business, unless it fills a market need – solves an issue, it’s probably not going to do all that well.
