In life we need boundaries. Buffer zones between people and situations that could do harm. Personal relationships need boundaries too for emotional and physical safety. Some relationships can become inappropriately intimate especially when there are attachments in the mix.
Bloggers need boundaries too. Connections are made daily and there must be respect of the personal situations of one another. I think we can be too open online and that can become a problem in an era when people aren’t so kind. As friendships are made through social media we have to be careful about how friendly we can be.
Form your own best practices but have fun. Don’t let yourself get into a jam online.
