Looks like the "Latest Blog Posts" have been replaced by "Latest Content."
While it may not show who posted the "latest content," (yet) this will make it much easier to see recent activity. Thank you communitymanagers for listening to our concerns and making this happen. If you can get the Jive folks to include the name of the person who posted the most recent comment and when, that would make this enhancement even better.
This has been one of the biggest complaints about the new Insiders site. I'm pleased to see progress on addressing the concerns. Thanks again and "keep on keepin' on!"
