Wow. I love this new “social reader” from the Washington Post.

Don Graham, chairman of the Washington Post company (damn smart guy who has seen a TON in the publishing world) and I talk about this.

We talk about porn, too. “I wouldn’t use this app for that,” he says.

Really interesting insights into why these IDENTITY ENGINES are going to change everything.

And if you think that Google won’t do this I have a nice bridge to sell you in San Francisco (Google is working on a new reader like this code-named “Propeller.”)

Ray Chan, Co-Founder and CEO of Singboard, and his partners arrived at 500 Startups with an idea for a photo-sharing app. After initial feedback for the app was luke warm, however, things changed drastically. Based on the fact that, according to Chan, karaoke bars in the U.S. paled in comparison to their native Hong Kong, the team regrouped, came up with a new idea and Singboard was born.

“Basically, Singboard is where YouTube meets karaoke,” says Chan. “It is a much more improved experience of online karaoke…We will get all the latest and most popular music videos from YouTube, and we will overlay the lyrics on top of the videos, and the lyrics will provide a karaoke-like feature, so that you can sing along with it and enjoy a really good singing experience.”

Singboard’s technology streams different content at the same time, allowing you to turn off the vocals on a video and play just the music. You can choose from among the top 100 music videos on YouTube, and, because the service is on your computer as opposed to on a machine in a bar, you can stop, rewind and replay songs as often as you like. You can even record your own version of a song and share it with friends on Facebook or Twitter.

Singboard will likely be offered to users based on the freemium model, where you can play a certain number of songs for free but will have to pay a monthly subscription fee for unlimited access. The app is currently in private beta, but Chan says they are pleased with the initial response.

“So far the feedback is really positive,” says Chan. “People just want to have more songs so that they can find their favorite songs to sing.”

Evri has another news reader. But this one has some seriously cool technology underneath. Here CEO Will Hunsinger gives us a bunch of reasons why its technology is better.

I’m loving this fight between a group of Flipboard competitors. Should Flipboard be scared? Yes – eventually one of these will figure out something much better than it’s doing and Evri has been working on news semantic databases for years, so this is a very good effort.
