I think perhaps the Daveverse server is not doing the rssCloud notifications for subscribers, because: 

• when i publish something new to daveverse, feedland doesn't immediately check the feed, as it would if it were getting a rssCloud ping.
• the rssCloud mechanism appears to be working properly for wordpress.com-hosted sites, and for Scripting News and other sites that support rssCloud.
• i find that if i cause the check to happen in WordLand (something it can do because it can talk directly to the feedland server) i get the notification via websocket and the update happens in the timeline.
• note that daveverse.org is hosted on my own server, with help from Scott Hanson.
• since this is being posted on daveverse.org it serves as a test case for me to confirm some of the things i said here. 😉
