Top "Big Data" accounts on Twitter

Which accounts should I follow on Twitter to stay up to date with Big Data?

This is a common question for those who want to learn about Big Data or know more about the field.
Well, it just so happened that I wanted to practise my skills with Python and with Twitter API, I have thus created a way to find and rank the most successful accounts talking about Big Data on Twitter.
Here is the Top 50, based on the activity in July 2015.

Some details about the score, for those of you who want to know more (and I am sure there are many).

• The score reported in the above board is a normalised score, where the 1st account gets 100%. In fact, the absolute score of the first account is 53% of the theoretical maximum. 
• The score is calculated by considering only popular tweets containing the hashtag "BigData" and putting together 4 different metrics, including the number of retweets, favourites, tweets and followers.
• The score in each metric is normalised to the user who performed the best in the considered time interval (July 2015 in this case).

Here are the Top10 for each of the metric considered alone:

1. As you can see KPMG built its victory on the number of retweets and favourites.
2. World Economic Forum's 2nd general position is mainly due to its large user base (2.6M followers).
3. CloudExpo makes it to the podium thanks to its intense activity.
