I've been a fan of discogs.com for years (so long in fact that my login name there is quahogs, a name I've largely left in the dust, thanks to the popularity of Family Guy). It has long been a great resource when looking up not only obscure acts, but also details on those that are better known.
They have implemented a new design recently (within the last few days, I think) that I think is a good improvement in both looks and utility. The thing that excites me most, though, is the smooth implementation of a youtube embedding function. No need to copy/past code here and there, just click "edit" in the youtube section of an artist or release, and go from there! I've already done a few that I knew I had my own uploaded vids for, but I am sure that whenever I reference discogs for an unknown artist I will be hitting this function to hear a bit of an example.
So, yay discogs!
Incidentally, their image "functionality" is either broken or too obscure for me. Take, for example, Dr Butcher MD: I added a picture of him I took at stAllio!'s wedding reception that is not yet showing up. Is there some voting link I am not seeing?
Same thing happened when I tried to add pcis for my friend Shiva. Any idea what's going on?
