Is there anybody who have other similar stories, with a big traffic spike for a short period of time ?
nice. i see there's a lot of people on the forum reading this...I came just to see how many replies you'd get. If people would spend less time reading that others are making $$$$ and getting out there and doing it themselves...they'd be catching dollars too
Nice job always if you are looking for a niche domain you will be able to do great money with AdSense. And of course, keep your website updated with news news and news. I have success in that way, and I don't intend to change my natural course of developing a website. Anyway that increase of users only for 1,5 days is amazing. Congrats.
