It’s a rather old trick but I’ve found it cool so I have to implement this trick here, call me a trend-follower ;). It’s called live comment preview trick.
What does it do? Well, right now if you are typing your comment here then your writen comment is directly previewed live under the “Post” button. So there is no need to have a separate preview page and you can see what is you are typing live. Neat, eh? Just a little addition to spice things up. Hopefully it will works across browser.
Done two things in one row and it just take less than an hour… phew.
