Ning Team I think I know what is wrong with some of the newsfeed problems.
Say someone signs up for a ning network with the name of network pumpkinsoap.ning.com ok so three months ago someone else also firstly created pumpkinsoap.ning.com they did not keep their network, so ning cancelled it. Ning should Delete all their Cancelled networks, because if you re create a ning name address that someone else already had its causing a traffic jam in some way on your site.
The newsfeed is sticking because of your choice in a name for your ning address.... bottle neck.
Just saying. Just totally delete all of the deleted or cancelled networks and start over fresh and I bet things start running smoothly again here.
You can put things in the trash can but the bag still needs to taken to the curb and emptied.
This issue is just another reason why I moved my site some place else. I like ning because I like the rss newsfeed option. I still want a 2.0 tho so if you are selling one please think of me.
