Well, it's not better, but something different. Before I go on, I'd better
say, that I prefer the GPL for my projects and in general. RMS himself has
written long articles regarding the differece between the LGPL and the GPL,
for example: http://www.fsf.org/licenses/why-not-lgpl.html

In a nutshell it boils down to this: Use the LGPL, if you want proprietary,
non-free software written with your library, use the GPL, if you don't want
this. Plus: If you have written a software/library, that has no commercial
alternative, use the GPL to strengthen the Free software movement.
Because then "we have something, they (the proprietarians) haven't".

The GPL hampers the developement of closed source (flext-)externals. You
have put a whole lot of work into flext and made it open source. I don't
see any gain in releasing it to developers, that wouldn't want to release
their source.

Although written by the FSF, this document is a great overview of various
open source licenses:

Especially important are the comments on "GPL-Compatible or not" licenses,
because there already are flext-externals written under GPL (mine and most
others, because currently flext is GPL), so they should be able to retain
the GPL in the future as well. 

Actually, I wouldn't bother much reading all those licenses. I don't see
real advantages to using something else than the (L)GPL - with copyleft
enforcing - or the X11 - proprietary usage possible (aka BSD, MIT) -
licenses for open source software. Most other licenses to me just seem like
syntactical sugar. And the Pd license itself looks a little vague in my
