Personally I like it! Going to try it for a bit.
You actually can try it out in incognito mode and any other browser. But we found that without the convenience of a navbar search, most people won't give it a proper try either way.
I hope we can drop this requirement even in Chrome when we become one of the default options.
If you set your search engine default to http://you.com manually in Chrome with "https://you.com/search?q=%s" you will not need the extension... but for most people convenience wins and well...
It's tough to go up against a monopoly that controls the browser too?
At least Chromium-based browsers have 5 second extension install/uninstall options whereas in Safari it's several minutes and so many clicks, we didn't even bother trying to build the extension.
Smaller browsers (if they at all exist) will default to Google because that's what users expect. Except Edge. Edge will stick to Bing.
You have an extremely memorable URL and in my view, the quality and accuracy of the results should naturally help spread the word for you if you do indeed provide a compelling alternative.
I'm sorry, I just don't buy your argument about "monopoly and controlling the browser" when you don't require an extension for those using Firefox, Edge, etc. - yet you _hope_ that Google will still add you to the default list of search engines.
So the idea was to force people using Chromium/Chrome to install an extension, driving off a huge percentage of power users with the hopes that the every day person (who couldn't even tell you what search engine they use) will adopt the extension without questioning it?
I don't think this is a tough choice. I think it was one you didn't think through at all.
