Early Uber investor and serial entrepreneur Jason Calacanis has launched an ad blocker

"AdReplacer" is a Chrome browser extension experiment from the Inside.com news site that seeks to block "obnoxious ads at the bottom of news stories" that link to "spam sites" by replacing them with "the best content from around the web."
--
The "quality content" that replaces the ads is curated by human editors.
--
On Twitter, Calacanis called out content recommendation firms Taboola, Outbrain, and ZergNet as the companies AdReplacer is going after.
--
AdReplacer isn't trying to replace all ads, only those it deems are "spammy." Calacanis says it represents a new category — "ad replacing" — which won't stifle the ad revenue of publishers as ad blocking does. Instead he hopes it will actually benefit publishers by sending more traffic their way (without them having to pay content recommendation platforms like Taboola, Outbrain, and ZergNet for those clicks.)
