My two cents (which are very much the same as the previous posters): I make music and post the occasional video to YouTube. I also post most of my musical output to Soundcloud. I maintain a bunch of different pages on different sites to support and promote my work and generally speaking find it much simpler if I can simply embed the YouTube and Soundcloud stuff on those pages (I do it on Weasyl, but sadly Weasyl gets zero traffic). I would think allowing embeds would work in Furry Network's favor as it would free up their bandwidth and server space since they'd no longer be in the business of archiving space and bandwidth-hungry audio and video files.

I have the same issue posting mp3s.
