The next new thing?

I’ve been writing content for the web off and on for a couple of years now. The main reason I say off and on is that many times over the years I’ve simply shut down due to either a busy schedule or just lack of ideas (blogger’s block).
Enter Plinky. I created an account a while back, played around with it for a while and sort of put it on the shelf. A little explanation first, the writers at Plinky send out user-contributed “prompts” about once a week. They are usually in the form of “Name three songs you will take on a road trip.” You can just create the list and be done with it, or the service will usually ask a follow up question like, “What do you like about each song?” or something like that. Before you know it, you’ve just created a blog post.
The reason I set the service aside for a while was there weren’t many prompts to answer. Now that it’s been a while, I’ve signed in and have so many new prompts to answer.
The nice thing about this service is that a lot of the prompts are user-contributed. So the more user’s sign up, the number of prompts available will multiply.
So the question, does Plinky have the potential to become twitter-esque?
