As I said before in a thread, Yahoo is now the default browser of firefox, so we will see a small incline in users. Where I think the kicker is going to come in at is with Amazon in the future. Look at the relationships between Amazon, Yahoo, and Bing. I'm waiting for these 3 to make a merger. With the decline in Amazon's stock, I don't think this is too far around the corner.
If this happens, you will see a HUGE turn around for Amazon.
First they need to make their browser just a little more user friendly.
If they followed Googles footsteps and simply used a homepage with a browser on it, they would do so much better. I'm just not trying to look at all of this nonsense when I am on a mission for information:
That being said. If Yahoo made a few minor adjustments with the way the user experience is carried out and invested a little money OR made a merger with Amazon, these guys could easily compete with Google.
