However, in the final results, the accepted votes for KNIME by KDNuggets were only 174 (http://www.kdnuggets.com/polls/2012/analytics-data-mining-big-data-software.html).
I cannot really explain this drop in the accepted votes, but here it is.
According to KDNuggets, the KNIME users for 2011 were 174.
The KNIME users who voted in the KDNuggets poll 2012 and that I monitored reached a peak of 259.
Considering that not all KNIME users voted in the KDNUggets poll 2012, these numbers show a very interesting growth of the adoption of the KNIME platform for data analysis.
