Currently Reading - Chrome extension that lets your email recipient know what currently are you reading. Currently, it supports Gmail only.

"Like many, I love reading books. A few years back, I came up with the idea of creating a browser extension that could let my email recipients know what I am currently reading. I developed the first version and launched it. It worked for about a year and then stopped functioning due to changes in the Amazon product API. Unfortunately, I didn't give it much attention at that time. However, one day I received an email from an English school teacher who expressed interest in using it. She wanted her students to use the extension to cultivate their interest in reading. Regrettably, I had to apologize to her, as I didn't have a solution for the issue until I eventually found a way to resolve it. After testing some initial code, I relaunched the extension.
