This is why I hate using third party sites to post media like video playlists and slideshows on my blog. They disappear, and sometimes take the content with them. Case in point: two sites I’ve used to post image slideshows here.
One, Imageloop, has morphed into ima.gy, exclusively mobile platform for sharing photos via iPhone and iPod Touch. Good for them. Bad for the content I’d posted there. (Which I can’t seem to access anymore.)
The other, Slide, is shutting down in March 2012. So, I’ve either gotta move it or lose it, content-wise. But really, why bother? It’s just as likely that I’m going to move it to another platform that will vanish as well.
That’s why I lean towards using plugins, frankly.
