おせわになりました。 I did a Search on this site and couldn't find a relevant answer, so my question is the following: As part of my independent study of Japanese I watch lots of Japanese language youtube vlogs, and fairly often I see w or ww or, especially, www, added to comments posted (in Japanese), and when they do appear, it's almost always at the end of the posts. IRC, I've seen these elsewhere on blogs like OK Wave as well. I had been thinking for quite some time that these "w" things were due to miscoding(?) by my browser, but now I'm thinking they're either actual emoticons or something similar. Could someone set me straight on this question?
