Hey James, duly noted. For now, the calculator only exists in a spreadsheet, down the line, we may well create a much sleeker web-based version but we wanted to ship it as quickly as possible while making sure it was valuable functionally.

I would recommend checking out the Segment Academy starting with this post: https://segment.com/academy/intro/how-to-create-a-tracking-plan/

While they do give examples from their product (it's great by the way) the fundamentals of data analytics are transferrable. I fully agree with Dexter W that identifying the questions you want to answer with analytics data is more important than the tool itself.

Interested in your thoughts on the 2nd point in this post "Make it quick and fun".

I think it's important that user onboarding goes beyond just the first use and a quick feature explanations seem to do a poor job of helping users be successful in a product.

I much prefer the principles outlined here by Samuel Hulick that focus on creating integrated experiences that reinforce value over time.

This post from AuthO has some stats on the impact of adding social sign up options -> https://auth0.com/blog/how-to-use-social-login-to-drive-your-apps-growth/

Personally, I think the impact depends on the type of product you are signing into and whether or not the product will use the data that social auth provides. For example, I would imagine an app like Buffer benefits from offering social login whereas I can't imagine logging into a financial management app with Facebook.
