Many of us have some cash to spend.
If we can agree on a favorite, we could pick a site that we feel sad that it went downhill (or never got a good start), and support it by buying ads and/or in other ways.
Here are two suggestions:
I liked the design of Click Corporation (and back then I didn't know it was unrealistic to send only 5c emails LOL).
LetterWealth had wonderful 'holiday hunts' last year - when I saw them I thought every other site would copy the idea.
And it has been around for over 2 years! But every now and then there are inactive periods, as if people forgot it exists and they don't buy ads..
sites like Zipper Clicker are nice (but e-gold gets a large chunk of all the payments, and as soon as we would stop supporting it it would be inactive again LOL); that's INSTANT advertising there
(edited: fixed an old typo LOL)
