Dabr does not have flashy icons or a huge splash page. It is because they are geared for mobile devices and providing the best web experience they can. oAuth is offered, but they openly state it does not always work well on mobile devices so a normal username/password login option is avaialable.
There is multiple color screens as well as selecting the type of client you are accessing the site:
- touch mobile
- normal mobile
- text only
- work safe
From there you can also go directly to external links of use Google Web Transcoder (GWT) to get small speedy pages. The conversation thread can also be reversed, when it works properly. The list of options of what you can view is pretty extensive once you log in:
You get the idea. I was able to see my lists I follow/created as well as ones that follow me. Take that for a mobile client supporting lists. Selecting any user profile gives me a nice mobile version of information about them as well as the normal ability to interact with tweets themselves.
This scores high on the mobile web interface for usability and features.
