Thought I'd summarize this topic as an "aide de n00b." To date, 97 different apps have been mentioned here, 27 of which have had more than one vote.
The Top 10 apps are:
1 : Ringdroid (10 votes)
2 : Shopsavvy (8 votes)
3= imeem (7 votes)
3= shazam (7 votes)
3= Weather Channel (7 votes)
6 : Togglesettings (6 votes)
7= aknote (4 votes)
7= Picsay (4 votes)
7= Tunewiki (4 votes)
7= Weather bug (4 votes)
Apps just outside the Top 10 include: atrackdog, compareanywhere, starcontact, and tag to do list.
Of course, newer apps are bound to have fewer votes, and I expect most of the 71 apps that got only one vote where voted for by their developer 
One surprise for me is that locale only received one vote and Google Developer Challenge $275,000 winners cab4me, Ecorio, Life360, Softrace, and Wertago have not received any votes at all.
