Yes - while radio signals are relatively cheaper to produce and can spread
out over a much larger group of targets, if you want to send a lot of detailed
information - including video images, which would no doubt help facilitate
understanding between species - and make sure you are aiming at a specific
place, then Optical SETI is the way to go.

Another advantage: Unlike radio with it literally millions of frequencies to
decide from, it would be hard to mistake a suddenly very bright star in the
sky, which is what Optical SETI can do.

Of course I think we should search for both radio and optical signals, as well
as the possibility of probes right in our Sol system, as we do not know what
an ETI might use for such communication.
