I don't have the feeling that google finance is live and kicking. I think it's one of those product that will disappear soon. There are lots of broken feeds like:
I actually went to google finance where I could get live price feed when yahoo and my bloomberg terminal had 15min delays. Now even yahoo has live feeds too.
1. It's because Google finance is old and probably forgotten. Really answers the OP question why it's not a good idea to kill flash right now.
2. Have been trading for a while and can tell that the performance of that chart beat the hell out of any JavaScript charting tool out there. It's interesting that JS/HTML 5 is all the hype now but it's still lagging behind a 10 year old technology.
Yeah, i do find it odd that Google finance (which is used quite a bit i believe) hasn't had any life breathed into it. I'm sure its had the same design for the last decade now
While they seemed to have abandoned Google Finance and left it in flash limbo, they do seem to be using HTML5 for stock charting whey you query google for: "company name" quote
