There have been nearly 1.8 million tweets about Pope Francis in the last day, according to digital advertising player and data specialist Amobee Brand Intelligence.

No small number of them have been hashtagged #pizzapope, in honor of the crafty work by New York's Bleecker Street Pizza (especially with the anchovies), which you can see above.

At any rate, using keyword algorithms to suss out whether the chatter has been positive or negative, Amobee's data suggest that the popular pontiff's visit isn't creating game-changing momentum for the Catholic Church on Twitter. So far on the social platform, sentiment around the pope has been 21 percent positive versus 12 percent negative—with 67 percent coming in as neutral.

Here are five other interesting stats from Amobee, which pulled its numbers from 1 p.m. Thursday to 1 p.m. today:

• Across the Web, the presidential candidate who has been mentioned most with the pope is Bernie Sanders—who, interestingly, as a Jew, is the only non-Christian candidate in the race for either party. Nineteen percent of all digital content engagement around Sanders has been related to the pontiff, as the two public figures essentially see eye to eye on the issue of income inequality.
• Meanwhile, with the pope riding in a Fiat as his Popemobile, that brand has also become identified with the visit—22 percent of all digital content engagement around Fiat has been related to the pope. 
• "Pope Francis" has been mentioned in 177,633 tweets.
• The hashtag #PopeInDC appeared 117,765 times. 
• There have been 110,169 tweets around  #PopeInNYC, but that number will likely grow considerably as the pontiff continues his New York stay until tomorrow morning—when he heads to Philadelphia.
