If a social login button is the biggest of your worries, god help your poor soul.
It's a sad day in the community when you detract from the release of this site by chosing to point out and upvote the negative feedback. The least you can do is follow the general rule of thumb to provide some positive feedback followed by any qualms you may have.
My first inclination was to comment this is a cool idea and was glad to see that it had integrations with GMail and Wordpress. For Wordpress specifically, there's draft mode, but that doesn't afford you feedback directly in context of an article.
Well, if the social login prevents him from signing up, he obviously can't even try the product. So how could he have any comments about the product itself, whether positive or negative?
Here's a less blunt version of @sixQuarks's complaint, which I think is completely valid:
Poetica has unnecessary friction in the signup process, and the very existence of this friction implies that the founders might not have thought long & hard about what kind of users they want to attract. IMO, people who write a lot and use Markdown to do so are more likely than the general public to be concerned about the privacy implications of social login and therefore wish to avoid it. Poetica also seems like the kind of product that could benefit from a quick online demo right on the landing page, but the founders chose to require signup first. Both of these factors are surely detrimental to their conversion rate.
I'd like to recommend to the author using Persona[1] as a (potentially extra) sign in solution. There are clear benefits to third party auth, but "social" authentication has its problems. Persona solves that.
Negative feedback is more useful than positive. Saying "nice site" tells the creator nothing. Pointing out a flaw tells the creator something possibly in need of improvement.
