Yes, forums outside this one that now have a cryptocurrency section or topics that weren't there before.

4chan now has a /biz section, which was originally designed to facilitate the rampant discussion of alternative cryptocurrencies .. that began with the excessive moderation of Doge and Stablecoin threads that were springing up like weeds. That section continues to maintain multiple conversations about cryptocurrencies today. Before that, there was a sparse mention of a bitcoin thread in the /pol section .. they were largely ignored. You may consider that these people would have ordinarily not have invested in bitcoin .. because these threads have been on that site for years and were'nt producing the effect like it did with Doge.

Reddit now has an incredible number of threads dedicated to alternative currencies, and are a staple of some communities. Thousands of pages of nothing but Doge.

Even obscure forums like SMD, and GameFAQS forums are now exposed to these alt coins.

The qualification that forums were exposed to cryptocurrencies like Bitcoin through Doge is an important one. You've mentioned many times that people always have to go through KYC/AML laws in order to get their hands on cryptocurrencies .. well in this case thousands of people grabbed Doge and in my case Stablecoin before ever touching bitcoin. I say thousands because just a few months ago I saw more than double the number of average users on poloniex trading as I do right now (770). These people were on constantly .. and now they're not. I feel pretty safe to say that a lot came for both the Doge and Bitcoin rush.

I feel this way because when comparing the Doge and Bitcoin reddits, there are 133,973 readers and 87,036 rich shibes. From those numbers, I'd say that of the 800 (that are now not there) that were there for the 'bitcoin boom', 39.3% of them were brought in mostly from Doge using only reddit numbers. This is 315 people out of ~1500. I'm making the point that there were 87,036 people that were interested in cryptocurrencies because for one brief moment there was a link to something they were already familiar and comfortable with - making fun of people on the internet.

If you're looking for more quantification, take a look at the site traffic from those sites .. because I'd be very surprised if most of these people didn't come from one of those sources. So yes, I agree that qualitative and quantitative demographics studies show that Doge "drew in new people who would not be attracted to Bitcoin", because the avenues these people took to get doge coin were, for the most part, already subjecting these same people to bitcoin (which they then ignored) for years.
