Ask HN: Is it wise to build products on twitters API?

I'm currently developing a heap of little apps on twitters platform and just as i finish one i get an idea for another.

Then i started thinking. Is it wise to dedicate so much time and resources into developing someone else's product. What's to stop twitter from replicating your product or limiting access to their API?

What do you guys think?
