I won't download this update because it modifies the web page.As a web developer I can't install anything like that because it will affect the apperance of clients' designs and that is unacceptable. I don't want to switch profiles to do this. If would be nicer if you could toggle it on / off but I doubt there's any way to do this, please correct me if I'm wrong.
An on/off switch (toolbar button and/or context extension item) is a prerequisite as I'm concerned. This said, the number of extensions whose function requires following the pages you visit is absolutely amazing.
I've been using this for about a week and I it's pretty cool. I haven't noticed any slow-down, and almost any page I go to has multiple twitter icons linking to somebody's recent messages. This adds another interesting layer to my web browsing. I highly recommend giving it a try.
This is a great extension and should be installed on all browsers. However not all twitter accounts are picked up and I can't find a way to alert the developers to this. eg Aberdeen City Council (@aberdeencc) doesn't work. Nor do many other councils. Even the mighty Stephen Fry, the most followed UK tweep isn't identified. Is there a feedback mechanism?
This is a gem I discovered through an article in today's (July 7 2010) Wall Street Journal. Very unobtrusive most of the time, but look carefully and on pages where there are celebrities, sportspeople etc, it adds a twitter logo next to their name and you can follow their tweets right there! I had my a-ha moment when I visited some World Cup articles and saw tweets from the players. I didn't even know they were on Twitter!
