Many people have their own websites and relatively unique names (or login names).
If your name is Bernard Something, you may own BernardSomething.com,
making com.bernardsomething.xxxx (or com.bsomething.xxx) a legitimate package name IMHO for personal code.
That being said, If your project name is unique, you may want to name the package after that.
And of course, get the domain after your name if you don't own it yet!
