So according to this and CiPHPerCoder's comment, the only reason it didn't take off is that it didn't take off? Edit: found the comment from Adam Langley [0].

So according to this and CiPHPerCoder's comment, the only reason it didn't take off is that it didn't take off? Edit: found the comment from Adam Langley [0]. They didn't want to add it to Chrome because it wouldn't meet standards for the preferences UI inclusion, practically everyone would just rely on the default notaries, so Google would have to guarantee notary uptime, thus being forced to run them on their own. He doesn't really point out why they don't include it as an optional alternative without any notaries pre-configured. He does however say that running it as an extension would be fine, but the required APIs weren't available at the time of writing. 0: https://www.imperialviolet.org/2011/09/07/convergence.html https://www.imperialviolet.org/2011/09/07/convergence.html
