Google Drive only works with Chrome Web Store apps? Strange. SkyDrive has SDKs for Windows Phone, iOS and Android apps at http://msdn.microsoft.com/en-us/live/ff621310

PS: Yes, I work on the SkyDrive developer platform. It doesn't change the truth.

It seems you don't understand what CAPTCHAs are for on a large site. The purpose of a CAPTCHA is to make it expensive for automated systems to make fake accounts on your site. If the CAPTCHA requires them to hire people via Mechanical Turk to solve it then it has done it's job. If it requires a one line JQuery statement then it is a complete #fail.

Bah, you must share the same IP range as a particularly persistent comment spammer I've had for years. I've disabled the redirect.

Sorry about that.

I've updated my post based on your comment above. Thanks, it was rather helpful.

That solution doesn't address my question. Caching @reply subscribers only addresses the 3% of users who have opted-in to receiving all @replies. For the remaining 97% whether they receive @replies from someone they are following or not is a function of which user the reply is directed to and whether that user is also their friend. You can't cache that, at best you can optimize how you calculate who should receive replies.

In fact, what you've pointed out is that building an implementation to address the 3% case is straightforward which was the point of my post.

PS: My blog does have a commenting feature. In fact there are 3 comments in response to the post.
