The site looks great! Unless you stole the layout ideas from someone else, you should be quite proud of yourself and what you've got started here. A few pieces of input: 1. Like others, the logo doesn't stand out. In fact, I didn't see it until I read some of the other comments and adjusted my monitor position a bit. 2. Emphasize the txt'ing capabilities a little more. Assuming you're using something like Twilio, why…
3. Already in the pipeline. Will be an awesome feature, I believe.
4. Pondering this, but it's a toughie. Trying to keep things simple, uncluttered, and easy to use while adding more features is one of the most difficult challenges I have faced.
The design and interface are completely original. What you're seeing is about the 4th major rendition over the past 2 months. As I am writing code I keep striving to make Pocket better and better (visually) and I'm pretty happy with where it's at now. We'll see how long it takes me to get bored =]
As for the authentication, I rolled my own (with the help of some tutorials) but I believe its pretty similar to authlogic. I'm sure I can add a password reset feature, but I just haven't had a chance to look into it yet.
Thanks for all of the kind words. The support here on HN is incredibly motivating and encouraging!
