I'll take advantage of my status as moderator of this site to promote a new community I've just created for my Android "Ping & DNS" (see my signature). It's at community for Ping & DNS on Google+, and I hope it becomes a place for discussion and feedback around the app as well as related subjects. I've just released a new version of the app with significant improvements. Stop by to say hello!
I'll further abuse this thread by mentioning that I've just released a new version of the app which adds as SSL Scan option that display a bunch of information about a host's SSL setup (some of which a browser will not tell you). See the link in my signature for the Play Store listing.
