Presumably none, since its only searching english wikipedia, and that looks to be belarusian.

I don't think most things are ever limited to one language like that. Also, Hacker News doesn't let you delete your own comments?

idk, it appears this thing is, since after clicking around a few times it becomes very obvious all the content is english. Guess that is just how the author of this project decided to make it.

Generally you can delete your comment if its relatively soon after you posted it and nobody replied.

do you get email alerts on comment replys?

or rss? im not really sure what rss is.
