Honestly, I think its a dud. You may pickup a small typo traffic, but considering Alexa is a free service anyhow, I would think this would be difficult to monetize.
So, if the case is in fact that this name gets almost no traffic, I see almost no value to it. Its strikingly similar to Alexa, and I think in the end - if you developed it, you woul be sending some typo traffic to Alexa, not the other way around.
