how can I get feedback on plugin I wrote on github ?

I am looking for a job and had talked to a company. The fellow there encouraged me to make available some sort of code sample of my work. I took some functionality out of a website I had worked on a few years ago and created a rails plugin which is now on github here:

Given that this code is part of my job search, I feel I should ask any good ideas on how I can get some feedback ?

Also, I am interested on where I could find ideas to write some simple plugins that might take a day or 2 to write or maybe even people who are looking for someone to write a plugin, gem etc.

I used to have a text to speech ruby program that would read whatever was in the paste buffer. I think I lost it when my old laptop crashed, I could probably re write it, it wasn't that complex. I used to use it to read text off of websites.

I am just looking for ideas to keep my skills going or improve them one way or another. I hope to make it to the ruby meetup next month as well.
