The forum is focused on all aspects of Bitcoin, and this also covers the economic aspect, including trading and speculation.
I do not think a price ticker would be in contrast with the vision of Satoshi, but it is not also a priority. And if implemented, I would suggest it shows the price of BTC only. As that is the price objective of the forum.
as long as it can be turned off. i like my pages static. for me, basically any movement is annoying.
I also don't think it's necessary, it's just a forum.
Why do you need a bitcoin real-time price when you can just google it (or see it on an exchange)?
If I log in my account, I would like to fully focus on what I read, and what I type to discuss. I agree with @redsnow and @vapourminer that dynamic movements from glitched-animated-avatars or real-time Bitcoin price are annoying. It is better to fully focus on one thing to do at specific moment.
If you want to trade, open exchange sites, log in accounts, and trade.
If you don't want to trade, or in the process of composing your posts/ threads here, while bitcoin market is boring (there is no reason to trade bitcoin), turn off all un-necessary sites.
It is true that we all are very easily to be distracted by annoying or attractive stuffs.
