My Thoughts
While multi-part questions are encouraged, IMHO posting multiple separate questions in the same post - that is, questions that are not all sub-parts of the same question and could be asked in a separate post - should be discouraged. I see three separate topics/questions in the linked post. I believe that these should have been added as three separate topic/question posts.
Multi-part vs multi-topic
###Multi-part vs multi-topic II ask a lot of multi-part questions, and I think that @HarshBaid did a good job of identifying that the issue here is not multi-part questions, but rather multi-topic questions.
Discouraging this practice
To add to @HarshBaid's list, including multiple questions that are totally independent of one another in the same post can also make it very difficult for future users to find the information that they are looking for.
I agree that as community members, we should try to discourage this practice, but I do not believe that in this particular case the comments led the OP to add additional quesitons, as those questions were also included in the post that the OP copied from on StackOverflow. Regardless, I do believe that we should do what we can to inform members that this practice should be discouraged.
