congrats on the sick growth guys. The choice of languages surprised me. Chinese specifically - do you expect these users to buy pro accounts? or is that simply about market share?
this is really the big issue; translating sites are easy. Providing ongoing support in 5 languages, means having separate dedicated support teams. I'm interested to see how they handle this.
my personal website is hosted on weebly. Jimdo.com has lot of better features though and excellent site designing widgets in browser. I personally tried to build same thing and then understood making these simple things for end user is PITA and demanding on my (limited) skillset
