I created an RSS feed of all the HubMob roundup hubs I have written. The roundups are on each week's HubMob topic, with links to the submissions for that HubMob. You should also find links to the HubMob forum threads and the RSS feeds in the roundups.
I have been doing the roundups since last Jan. Shirley Anderson did HubMob roundups before me. You could go to her profile and search HubMob. I would also suggest messaging Princessa. She has access to metrics and stuff that I do not.
