ACCEPTED ANSWER

Score 41

i would do this:

start recording a macro 'q': qqJjq
replay the macro 'q' 500 times: 500@q

(actually it is not a macro called 'q', it is a named register called 'q'. instead of interactively fill that register as in 1., you could also do :let @q = "Jj" and then do 2.)

ANSWER 2

Score 38

To do this on every line of the file:

:%normal J

or, shorter:

:%norm J

To do this on just a portion of the file, select the lines with V or get a range some other way:

:'<,'>global/^/normal J

or, shorter:

:'<,'>g/^/norm J

ANSWER 3

What about this:

:g/$/j

:g/$/j!

and group every three lines

:g/$/j3
