I'm invested in Google's open source project hosting. I use it for Guice, Gson, DexMaker, MockWebServer, Shush and several others. I'm using all the features: issues, wikis, downloads. Migrating away will not be easy!
But Google has lost interest. They haven't mentioned project hosting on the Google Code blog in over 3 years. Google Glass was released on GitHub, and this week they deprecated downloads.
I won't be starting new projects on Google Code.
