JAVA Influencers 2019

JAX London, 7-10 October 2019
The Conference for Java & Software Innovation

Aug 19, 2019

Who are the most influential Java people in the Twittersphere? After analyzing thousands of accounts, we created a list of people that every Java enthusiast or pro should be following.

All influential people have something in common: they can spread ideas faster and better than anyone else. We are aware that following these people has a handful of perks, including staying on top of the latest news and trends. Therefore, we decided to concoct a list of Twitter accounts all Java fans should follow. The analysis ranks the top accounts in accordance with their social influence, although interestingly enough, not all household names of Java evangelists are on the list. Nevertheless, we are very proud of the list that we came up with.

This year we really looked for the right combination of quality content, social credibility and a strong voice in the community. There are some big names in the software development world many of us probably know of and some of them do have a wide reach in in the Twittersphere, but we were looking for the ones who make a change today, the movers and shakers of Java in the social world in 2019. We decided to save the honorary spots for two names we are sure anyone in the Java community appreciates, though we didn’t add them to the infographic so we could really focus on the grassroots level of the Java network.

Congratulations to all influencers who made it into our Top 20 list. Click on each username to visit their Twitter accounts or the list on twitter. Below our detailed list, you find our methodology and insights how we created the ranking.

We first generated a list of twenty thousand Java-related Twitter accounts (including all accounts that contain the keyword Java in their bio or in any of their tweets.)
To score the account and rank them accordingly, we analyzed their social authority and reach using two key metrics: MozRank and Kred.

Moz Social Authority Score: Social Authority score is composed of:

    1. The retweet rate of users’ last few hundred tweets.
    2. The recency of those tweets.
    3. A retweet-based model trained on user profile data.

Visit this MOZ blog post for more in-depth information.

Kred Score: Kred Influence Measurement, or Kred, is a website created by PeopleBrowsr that attempts to measure online social influence. Read more in the Kred scoring guide.
