Data Visualization Poll (Fall 2011)

7 months ago I published a poll on LinkedIn and got a lot of responses, 1340 votes (in average 1 vote per hour) and comments. People asked me many times to repeat this poll from time to time. I guess it is time to re-Poll. I added 2 more choices (LinkedIn allows maximum 5 choices in their polls and it is clear not enough for this poll), based on a feedback I got: Omniscope and Visual Insight/Microstrategy. I also got some angry voters complaining that certain vendors are funding this poll. This is completely FALSE, I am unaffiliated with any of vendors, mentioned in this poll and I am working for completely independent (from those vendors) software company, see the About page of this Blog.

  • Tableau's approach to Partners is from stone ages

  • Tableau is 2 generations behind Spotfire in terms of API, Modeling and Analytics
