My point is not that it shouldn't be there again, it's that some potentially interesting stuffs have already been discussed, so the previous thread is probably worth a look too.

You should put that into your first post :) Most of the time I see post like this meaning it was a double post.

My preferred format is: https://news.ycombinator.com/item?id=10317790 (1254 points, 157 days ago, 366 comments)

Because it answer most of the common questions about a resubmission: Did it get a lot of exposure? Was it a long time ago? Did it have an interesting discussion that I should read?

The number of comments actually doesn't show if the discussion was interesting of a flamewar. So I sometimes cherrypick some of the most interesting comments and repost a snippet.

(In this case, I think the most important comments are:

- The relation between the progressive and an extension for lossy mode

- The advantages and problems of the (L)GPLv3 licence

But each of them deserve it's own thread here.)
