Is Yahoo still has a chance against Google?
Recently, Yahoo has taken a little back. The interface card is very improved. This site is great. I've always used Yahoo Sports (audit teams, fantasy) and chat, but have recently lost my dedication to research, and consequently its coveted status page. I also noticed that Yahoo is in the process of "tuning" some of the innovations Google, but Google still appears ahead of the curve. Yahoo niche is enough to keep, or will Google win in the final. What do you think? N: Maybe you can fill them all, but you can buy, right?
I think there is room for Yahoo or any other competitor to Google. Google is certainly below the search market, but Yahoo is the web portal market locked. Will never be a single Internet conglomerate – too niche to fill.
