As someone that over the last year has bought 4 banjo ukes and a baritone(no sopranos though).. YES!!! . I definitely think interest is growing. It's the music has much as it is the instrument, since Uke music (IMHO) seems to be sort of don't worry get happy stuff (I can't stand THAT song, but the term seems to apply).

Re-issues of Cliff Edwards help too.

There also seems to be sort of a alternative uke scene in L.A., I don't know much about it, and don't even really like what I've heard on MP3.com of it, but it's there.

So even if you don't like the instrument you have to admit that all of those tunes from the 10's and 20's are pretty cool.
