I found the reason:
If someone edits an orginal post (then press post button of course) and after that uses browser's back button for navigation the post disappears.
It happened in my case...
Just wanted to let you know that the results from KDNuggets are in. RapidMiner was voted the most popular general platform for machine learning / data science with about 33% of all analysts using it. This is an awesome result!
Many thanks to all who supported us in this poll - you are the best!
Rapidminer has a thriving partner program and you can register yourself here to get directed to one of our Partner managers.
If you know someone who works at Rapidminer, do not hesitate to contact that person to get you connected also, but the web form I linked will help you automatically get into our internal parter maangement systems and will speed up other aspects of relationships.
Thank you and looking forward to work with you and your team
why do you think it is disbanded? It is not. Some of our active partners are also posting on this board like Balasz or John. Just drop me a private message or email at mschmitz at rapidminer.com. I am happy to connect you.
