I totally agree. However, I believe it is likely that when small-LISK hodlers first enter the network, they will likely to seek out profit first (can't deny I am also one of those...).
Once they earn some profit and obtain a decent amount of knowledge through discussions and self-learn, I think many of them will have a more "good-will" approach to the delegates system. And thus, will be more keen to "vote" for the right delegates for the sake of the community :).

My guide here will act just like a "hook" first for those newcomers only :D. Thus, I will continue to research and put together a more (hopefully) comprehensive guide on delegates' contributions.
