Nobody cares why you follow an influencer

The rise in popularity. of social networking sites in recent years has led to a corresponding growth in the number of influencers.

Some people follow influencers for positive reasons (e.g. they admire  their fitness/beauty regime). In other cases people follow influencers that they dislike (e.g. people might follow Andrew Tate so they can criticise his statements). However, the sponsors who pay the influencers don't care why you are following someone - they simply care that you read the influencer's posts.

You should be aware that if you read postings from someone like Andrew Tate, you are effectively paying his salary.

Pressure prediction analysis

Previously, I analysed how accurate various weather prediction services predicted the temperature a number of days in advance. Today I will look at their predictions for wind speed.

Here is the summary data

Here is a chart of the data for people who prefer visual:


Points to note
  • Openweathermap seems to be the most accurate by far.
  • Yr.no has similar accuracy openweathermap for one day in advance, but when predicting further into the future both darksky and yr.no are similar.
  • The error from openweathermap seems to be much larger than other services. I checked and this error is genuine.

Like the last time, this analysis lumps all cities together for an average result. I might do some analysis later on performance per city.
