If you're writing a large library of code which you want to see other people used too, picking a license is a very important thing. We were standing for the same choice for our eZ components . Originally we were using the LGPL as this is more in line with the GPL that we currently use for eZ publish . Now just before the release of the first public beta (in a few days, stay tuned) we decided to switch to the New BSD license. We feel that choosing the New BSD license would make it easier for people to use the components library without having to worry about the restrictions of the LGPL.
