About Alexa and traffic, i don't know if you knew this, but visitors who come to your page with the Alexa toolbar will give you more benefits. That's why some webmaster sites have good Alexa, but really not much volume, it's because most of it's visitors have the alexa toolbar installed. As for me, i have 1 solid website @ about 50000 alexa, and my 2 new websites are between 600 000 and 1 800 000!
mine is at 190,000 and keeps going backwards. not sure if that is a good thing! must mean more regular peeps are visiting? I don't know.
Was jumping around for a while. Now at 219k. Our traffic has actually doubled however I'm not seeing much of an improvement in Alexa. Maybe it'll follow in time.
