Hi Ratter,
This is probably the most difficult and unhelpful way I've seen a question posted in a long time :)
The problem is that you're experiencing slow typing in the "answer here" box?
I have this problem on Facebook sometimes - it's an issue which relates to the js code used to produce this box.
Sometimes it's to do with the browser cache.
It could relate to adverts, sometimes.
It could relate to having 15 tabs open at a time.
It could be because of lots of youtube videos being embedded on a page.
It could be the memory leak problem which occurs in FF and Chrome.
(I'm just saying, there's a lot of issues it could relate to!)
I suggest, if you experience this problem, that you should close down the browser, wait a second or two for it to completely close, and then open it again. This is likely to speed it up a bit.
