When you say "common theme" do you mean a particular subject or niche we should be discussing (that we have expertise on ) in our comments and posts?
Yes, a common subject.
Take for example @firepower.
If you look at his posts in the last 3 months, you can see 3 themes:
- steemit.chat where he is an admin (founder or co-founder?) and organize the Steemit.Chat Contest.
- Cryptos and social networks in India
- Let's Talk series, which this post is part of.
Another example with @sweetsssj:
Two series of posts that have been going on for months:
- Miss Delicious
- Travel with me
Another series, that she seems to have abandoned:
- Miss opinionated
That is what I mean by "common theme".
