Nothing to tap on when visiting other towns?

Thanks everyone for the helpful information. I didn't know it was possible to check when the last log-in was for each neighbor, or that the gremlin sound means they haven't updated. Turns out some haven't been on in over 2 weeks. I don't think I'll be deleting anyone yet since my friend list is nowhere near full, but at least now I can tell which ones to not bother with checking back later in the day and which ones to check again at different times. I guess I'll have to clear out the handshakes and graffiti whenever possible since I don't have the money or land to put extra duplicate buildings specifically for others to tap on when visiting. I'm so far behind with the main quests. >_< Already level 30 and I'm still trying to scrape together enough cash to build level 20 stuff. I think it might be because of event quests giving event items instead of money with the exp. Plus the writer's building costed so much more than anything else I had seen up to that point, and I was afraid if I didn't get that ASAP it would stop being available after the crossover episode aired on TV. @_@
