I would suggest that if someone leaves comment on your blogpost, you should return a favor, read his/her blogpost and interact.

It would be nice to have a strong bonding among each other.
We can give insightful advices and tips how to solve problems.

As for forum and groups that you had created, it would be nice to reply to your members’ comments.

Try to reply as many as possible.

As least they know that their comments or suggestions are listened a, not ignored by other members or the creator of the group.

What do you think?
