If you REALLY have to go the free route I'd go with the FreeHostia "Chocolate" plan @ Chocolate - bannerless free web hosting powered by advanced cluster technology

It's bannerless and pretty reliable for a free option.

Many Free Hosts don't hang about for long so be sure to check their terms of service carefully & backup frequently.

You can always find great quality web hosts for less than $7 per month.

I would just find cheap hosting. You can get decent hosting for around $4-5.

I agree hosting is very cheap and there are many good hosting companies around.I certainly wouldn't get involved with free hosting at all.

After doing a bit of research I found that a few free hosting provider take 50% of your revenue. No wonder it is free. Which web hosting provider do you guys use? Why?

I think people should stop considering free hosting. There are very cheap shared hosts out there.

I have a few blogspot blogs (4+ years old), still make $$.

Also, If you go with blogspot, a few rules to live by:

1) comment on another blogspot blog (just don't do it)!

2) Have real content on your site that you created (don't scrape other sites feeds).

3) Always follow the Adsense TOS, no matter what host you use...
