Posterous Way

Should I use Posterous? In part, that depends on how it copes with MP3 files. The FAQ specifies up to 1GB of space, but doesn't mention any limit on each MP3 file. Several services (Tumblr, for example) have a 10MB per file limit, which seems insufficient even for a voice-only podcast.
Anyway, let's email this to Posterous and see how the resulting blog looks.
