How can I accept Bitcoin donations on my blog or site? If I sell things, there are many services that allow me to accept bitcoins as payment.  But for those who simply want to accept bitcoins on their blog or other site ... as donations.

A simple bitcoin address can be listed but what other options are available, such as an icon that can be clicked on, like what Flattr offers, perhaps?
Although bloggers could turn to an external service to manage this for them, it might be more beneficial to simply offer a simple QR code with a description alongside. This would mean that all of the income from the BTCs would go direct to the blogger.

My personal blog has an article describing in detail how to do this. I'm not trying to plug anything honestly, just sharing knowledge. 

This can be imaged with a Bitcoin wallet, or dragged like a Bitcoin swatch onto the Multibit client. A simple click will trigger a protocol handler within the browser (if installed) that would activate an wallet plugin.
