I got the point. They're to make it easier for articles of certain criteria to be found. The reason behind might be vary. On Steemit, the main reason is to get visits from curators to have the opportunity to receive appropriate rewards.

I want to ask you this, do you, ishayachris, have any favorite hashtags that you used often? Would you tell me about it, like the reaseon behind it, your story with the tags, something funny maybe?

And please invite 3 friends to join the discussion as a requirement for me to include your name in the raffle list.

Thank you.
