@OP It is simply not about what you want. What you are trying to do, by your own admission, is prescribe methods for being optimal because it's gratifying to you. This is how you elect to spend your time. What escapes you then is that not everyone has the same aim/goals as you for when they join. Some people are content to not bother themselves with the effort required to be optimal but have more fun just playing it loose. Or some people prefer to learn things at their own pace and having other people dictate to them is distracting.

Point is, offering help is beautiful, but only when it's specifically asked for. If it's not being asked for, it shouldn't be baffling to imagine ways it can be seen as imposing instead. To the argument that they're impeding the party, then by all means, vote dismiss. That said, it's my belief that it's not our place to tell other people how to use their time unless they ask directly. For the 27 people who liked your post, this escapes them as well.
