None of us want more email, but the Photojojo newsletter might be an exception. Twice a week they give you “photo tips, DIY projects, and gear.” They are, seriously, quite cool.
For example, it is through Photojojo that I found out about the Photojojo Time Capsule, where each month you are sent photos from your Flickr stream from one year ago. Sounds basic, but it is cool. In addition, it through this newsletter that I first heard about the Eye-Fi which can “upload photos automatically from your digital camera to your computer and favorite photo site with the world’s first wireless memory card.”
If you like photos or photography, I suggest you check it out. (And, yes, they have an RSS feed. 🙂 )
