I am not so sure, since the GPL and LGPL are quite commented, so the general
outline is probably understood.
It is in the details that programmers are probably confused. Like putting
[L]GPL software in DLLs or shared libraries, etc.
I agree fully with the "confuse, hard to understand and virotic" (viral?)
statement! A lot of licences needs to be:
1) native English speaking;
2) versed in the (US) laws
to fully understand them.
This can be useful to avoid twisting the meaning of these terms, to provide
a firm ground in case of trial. But most users just want to know: "Can I
include this software without releasing the source code of my application?".

Personaly, I chose the zlib/libpng License which is short and clear. I could
have chosen the new BSD or the MIT one, quite similar.

Suggestion: take one well known licence, and apply some restrictive clauses.
This way, users immediately know the kind of licence you use (aha, it is a
MIT one!), and the special clauses that apply to the software (oho, I can't
call "Lua" my own special derivative language).
This may not dissipate the fog about licence compatibility, but it can be an
improvement. Or not :-(
