tDash was sent to us to check out, so we did as expected. Dug in to give you the review. For starters, they use oAuth for login and promise a clean, simple interface. URLs are automagically shortened and you can also share pictures. I was curious how the interface would look. The left side broke down to:
You can view a screenshot of the dashboard right here. Some alternate abilities were in the toolbar at the top including reordering how tweets showed and advanced tools like direct messaging. An unread count next to each friend name was also available to see how much they have tweeted recently. I am not sure how far back it goes or how it keeps track. Each users is treated as a folder, and you can mark a folder as read.
Selecting a folder also gives you info on the person and their avatar. Sharing a picture brought a pop-up window allowing you to browse to your local computer and place some description. Allowing me to grab URLs of pictures on the web would be cool too. The very bottom (scroll if you have lots of friends) shows the API usage and what tweets it is pulling in.
Ok, in summary then. A clean interface yes. Some unique features with the folder idea and read/unread. A killer web based client? No. A useful one in a pinch, yes. I know they are in early stages, so we will check back when they do more updates.
