It is important when posting to the chain to make it as easy as possible for the reader.

We do not know what you are thinking when you use generic labels for these things.

In this case, now that you've explained it, no, I do not think you should use two accounts in this case, because they are very similar.

On the other hand, if you wanted one account to talk about Schrodinger equation; Riemann Hypothesis. Educational programmes, educational system, plans, policies, laboratory activities...

...and a second account to talk about your favorite hobby, like how to cook a good piece of meat, or how to catch a fish, (Which has nothing to do with the other stuff) that's fine.

Where people err with multiple accounts, is if they create them with the sole purpose of upvoting themselves back and forth. That would be considered stealing from the reward pool.

When possible, do try to stay with one account, unless the second account is VASTLY different with the content.
