Dude, why are you asking Twitter? Twitter is where people go to be stupid. Ask Manifold. 

 I suspect virality is not a real disadvantage because the chance of the official manifold account making a viral poll are very very small. 

Conversely, anyone making a manifold poll that would have been a twitter poll otherwise is potentially bringing people they show the poll to directly to your site. 

Manifold polls sounds like a potential eggbasket violation. 

(Non-serious aside: getting opinions on this via a poll reminds me of a comic I can't find where someone is showing a powerpoint slide with a bar graph of responses to a survey about answering surveys. "I diligently respond to surveys" vs "I throw away surveys without looking at them". The person pointing to the slide is saying "it turns out our customers LOVE answering surveys!". See also 

 I'd also predict a sizeable jump in user engagement if/when this launches

Yes please. Couple them with a 'What will be the outcome of this poll' market to make it more Manifoldish (Would mean hiding the poll result till the poll outcome prediction market closes)

Advantages of building out Manifold-native polls:

Aka what % of people will choose "Yeah ofc" in this twitter poll:

#	Name	Total profit
1	David Glidden	M$4
2	Niklas Wiklander	M$0
3	Charlie	M$0
4	Colton Lewis	M$0
