If the user of the website "Schoolmates" wants to involve as much as possible commentators on the personal page or on the page of the group created by it (the second case it is normal more relevant), you should not look for difficult and syllogisms for this purpose. Councils for increase in number of comments are simple and logical.
How to make many comments on the personal page
Participants of social network usually comment on those posts which attracted some interest of them: video, photo, text messages, musical files, etc. Respectively, that to the ordinary user - "schoolmate" to involve more commentators on the page, he needs to implement two clauses:
1. Make as much as possible friends on social network. Virtual friends see all news of each other in the news feeds. Or it is necessary to visit specially a page of a profile of some participant of social network to see all its "gestures" on the website.
2. Spread whenever possible interesting content drawing attention: rare photopersonnel, good movies, substantial text posts, etc.
Of course, interestingness of content is defined by target audience and if at the user most of friends on the website "Schoolmates" are far from the world of art, hardly they will evaluate and will want to comment on the publication in which the author tells about the future chamber concert of the famous cellist, the new arthouse movie or great art installation. If the author wants its notes on the website to be commented, it is necessary to base on the interests of the friends.
If the user of "Schoolmates" wants to involve as much as possible commentators on the page, he also should not do the profile unavailable to viewing users of social network not of the list of friends.
Problem usually that one user can have friends with various hobbies and interests. Very difficult happens to understand what publications will be attractive to such speckled group.
