I'm not sure how many people are aware of this thing called Tab for a Cause, but it's really cool and needs to grow. It's a browser extension that simply replaces your "new tab" page with a new one with some ads on it and every time you open a new tab, the ad money collected is distributed to charities.
The new tab page is customizable so you can change the background picture and add shortcuts and bookmarks to whatever you want. Here is an example of mine:
You earn hearts from using it and then can use those to vote on charities. At the end of each quarter they give the ad money to those charities based off of how many hearts each one receives. Pretty simple, and it costs you nothing. If you haven't already, I'd suggest checking it out.
This is actually a really cool idea. I have been playing around with something like this to give more money to linux developers.
I gotta do a little research on this to make sure the money is going to the right places, but I will definitely be installing this if I find that it is an honorable charity.
There is a Q&A section https://gladly.zendesk.com/hc/en-us/categories/201939608-Tab-for-a-Cause
The site was set up by the nerd fighter community, (through the vlogbrothers on youtube) which I trust and as far as I can tell there is no reason to suspect it isn't real. The rarities they give to are listed on their site as well, organizations such as Save the Children Water.org and Room to Read are a few. The post their financial information online as well so you can go look through that: http://tab.gladly.io/more/financials
So lots of memory + ctrl + t = profit?
All the bot possibilities.
I guess??? Not sure how they track it. If the sponsors go by clicks or just views?
