No,you cant get adsense account without a website. and adsense will rejetc your application if you use free sites like blogger.
The whole point of Adsense is to put ads on websites. Hence they won't approve you if you have no website.
docstoc is a bad option as you'll be sharing revenue. blogspot/blogger is a good free option and I got approved like that.
you can apply adsense through some adsense sharing website like hubpage, xomba ... what you need to do is to write one good article and wait for a week or so to get approved
now days with good website you can not get the account whom will give u account of adsense without the website.
Now I am creating a new website for the same and i hope to get something out of the same. Thanks everyone for your kind words and suggestions.
yes it's possible if you have a blog. but the application will be easy if you have a website with traffic
"It might have been because the targeted side (blogspot blog) had lack of traffic" I do not think Adsense account depends on traffic
without a website u can try any revenue sharing sites to apply but its safe u have applied from any website with some content on it !!!
