You wrote 513 characters about a subject you don't know anything about. Why is that ? You didn't use dropbox, you don't know how it works (hint, what made it so popular is the desktop client that syncs your data in the first place. And it's written with wxpython.), but you felt compelled to write 513 chars about your ignorance and wild speculation ("Maybe in their earlier days blabla").

Then comparing apples to oranges "I use Ruby for light scripting" vs "widely deployed desktop app with users from the three major desktop systems (Windows, OS X, Linux)."

This kind of behavior is a serious annoyance in online discussions.
