The board for now is used as the supplement to my blog at http://www.cobrasmarketview.com
for 3 major purposes:
To post intraday comments about the market as the post here is much easier than that of blog.
The blog's comment area doesn't support posting images while in lots of cases a simple picture is worth hundreds of words. By using this board, now you can share images easily.
If members in this board is large enough, a poll now and then to measure the market sentiment may worth a lot while I cannot simply do it at my blog.
