Definitely not - among other things - for social/political reasons. Russia has occupied central/eastern countries for four decades and most people prefer to be as far away from it culturally as possible.
Even though my parents' generation was all forced to learn Russian, the current generation doesn't learn it. Even if it would be practical.
Also, Russian may be easy to learn, but it won't be easier to understand than my native Polish to my Czech and Slovakian friends. Interslavic on the other hand would be understood relatively easily.
I just read a chapter from the little prince that's on the page, and I understood it almost perfectly with no training in Interslavic, just with my knowledge of Polish language.
