Indeed!
And I guess to answer my question, I will echo pretty much everyone else's sentiments. I love the community that Kumoricon has formed and has become. It feels like a family reunion, coming back every year. It is warm and welcoming, no matter what may be going on throughout the rest of the year.
Also, I love the cosplay. I couldn't imagine a convention, let alone Kumoricon, without cosplay. It gives me something to look forward to, something to plan and create and collaborate with friends on, and then I am always amazed, inspired, and (sometimes) terrified and permanently scarred by other people's costumes. And I like that. It is fun and, I love how Kimiski put it - "Cons have their own heartbeat." QFT.
