Definitely need more delegates to update their feeds more regularly.
I want to add feed info for each delegate to my website, but there's an issue with the command "blockchain_get_feeds_from_delegate" which causes the client to freeze and lose all connections if you batch call the command for multiple delegates. I've registered a github issue for it and Vikram pushed a fix, but either it didn't make it into v0.4.16-RC2 or it didn't fix things. Once that issue gets fixed I'll have the info available on my site..
For now you can always find the feeds per asset on the individual asset pages.
