I've released all of my open-source code -- with the exception of one project (LGPL, because it was a direct port of another LGPL'd library) -- under permissive licenses like Apache 2.0 or modified BSD. What I really dislike about that feeling you describe is when I think of a good project I'd like to build, but which would require the use of a GPL'd library -- therefore requiring me to license my code under the GPL. Every time that's come up, I've just opted not to create the project; in my mind, I just can't justify writing open-source code that's "free" instead of free.
