I also use FLAC exclusively now. Space is not a problem any more and your archive can be used in many situations - different players, parties, as samples etc. Its not worth thinking about it. Furthermore, people that share FLAC are way more pedantic about their archive in general - like checking for re-encoding low quality mp3s, file hashs etc.
