I don't spend a lot of time on social media but Instagram is probably my favorite. I enjoy it's simplicity. Tinpin is my own pet-project to see if I could create a web app that allows you to create customized pins and magnets from your own photos and using Instagram photos. Before it launched, I called it Pintin but changed it to tinpin before launching - it's a good thing I have both domain names. While this is simply a side-project of mine, I try to find a little extra time here and there to keep improving the online user experience as well as it's products.
