Can a monthly subscription business be build on a Google extension plugin. I have an idea for a google extension i wanted to know if you have seen any one charging a monthly service fee for extension.
yes rapportive is great, i use them. they have a lot of buzz but are at the mercy of Google. Google can kill them any day.
As long as they are small, google will let them be, if they become big, i think google will complain because they are removing there ads.
Google won't complain: the users are actively installing a browser plugin on their own computers by choice to remove the ads, but more importantly get a great beneficial service.
It's no different than installing noscript or adblock on Firefox.
Yes, absolutely, but do make addons for Firefox/IE too. See videos of the Add-on-Con conference, lots of people talk about their experiences building business on top of browser extensions. http://addoncon.com/
