I have to say YES, Tamatown is boring.
I realize that the folks at Bandai are extremely busy, and they have all sorts of other things to do, but it wouldn't be all that difficult to do a minor update once every other week, or even once a week! I'm not talking about opening a major new section every week, nothing crazy. They could make it so that, once a week, you could get a new free random item, but you had to search the various areas to find it, like a scavenger hunt.
I've owned tamas for a month now, and I got bored of TamaTown in the first week, and there have been no new developments since I started. Is one little update a month too much to ask? I'm sure Bandai could give a little tidbit now and then, just to keep things interesting.
