Not bad at all. I've been through this a couple of times.

Generally, you are a lot more likely to be successful with something fun or entertaining than with tools and utilities. Now you can use the success of your chrome extension to promote other apps you've built!

Thanks! Definitely :). My goal is to create lots of super fun apps and on dooms day I will troll ALL of them and point them to the app of my choice. Jk :)...

But you're right, cool things can be used as a great platform to promote useful things.
