Google to offer RSS email
Well, everything seems to point to Google offering a new way to check our mail: RSS (more exactly, ATOM).
The link to the ATOM version of my GMail was up this morning but had been removed by tonight. I can still access the feed page, but have been unable to read it using a regular RSS reader (tried Bloglines, Rocket, RSS Bandit and SauceReader).
Presumably you’d be able to check your e-mail using any news reader (or a Google-specific one, perhaps but unlikely). Clicking on a message would open it in a browser window, with all the regular GMail functions for replying, forwarding, etc.
At this point, this is just speculation based on having seen the actual feed link.
