Brave is just another Chromium-based browser. It allows you to use the BAT token and blocks adds automatically. It's good and fast but not that much different from Chrome. To use BAT to tip content creators, you have to use Brave. Mostly everyone uses Chrome so they don't have to switch browsers in order to use Wildspark.
Brave looks more like Firefox than Chrome. Everyone has its own preferences but personaly I prefer firefox over Chrome. At the moment it looks odd to use another browser but maybe that's the purpose. If they are succesful then people could dump Chrome and Firefox and use Brave instead. But anyway, I don't think the "they don't use Chrome" is a reason for them to fail. But anyway, the whitepaper states the following:
The BAT will, in early stages, be specifically tied to Brave browsers and Brave servers, along with verified publishers.So it is not set in stone that it will only work for Brave. This is just in early stages. Just like WildSpark now only works for Chrome but might in the future be extended to work on other browsers.
You can't earn from tipping content creators with the BAT token like you can with AMP. In my opinion, BAT's tipping platform won't gain traction unless the team made a Chrome extension and gave users some sort of incentive as well. Your thoughts?
I don't think this is true. I see following formula in the whitepaper:
Publisher revenue = Advertiser buy in - User share - Brave placement share. I don't understand 100 % how it works but it looks to me that the money comes from the advertiser and that the user gets a share of the advertisement money when he surfs a page on which an addvertisement is displayed. So rewards here will work different than Steemit or WildSpark but users will be rewarded also.
