... I will be adding a monthly dividend payout at the end of this month. I am looking forward to the API. If it does not come out soon I may write something that will just take the twitter feed and do this automatically for me. I have never looked at the Twitter feed before, and doing it now I don't see any notification of dividends. I only see trades, but I will keep an eye on it.
You'd be better off with beautifulsoup or similar to screenscrape until the api comes out, which was supposed to have been by now. Dividends are not recorded in the twitter feed - might be worth getting nefario to add.
There is also an IRC feed on #bitcoin-assets-trades which lists in the format,
[22:24:07] <+`MBot> [ GLBSE ] [ TRADE ] [ FPGA-EU ] [ 2 @ 0.36 = 0.720000 BTC ]
[22:24:45] <+`MBot> [ GLBSE ] [ TRADE ] [ PUREMINING ] [ 2 @ 0.37 = 0.740000 BTC ]
#bitcoin-assets also has chat in it about glbse and mpex, along with the ability to get volume information with the command !ticker
