Hey cheers,
In terms of posting you can always do both, on two accounts if necessary.
It's worth exploring all the avenues certainly, and if you did want to get a game up and running, Hive would be a good candidate - eXode is a risky investment, but it dow look very interesting and potentially a lot of fun, the cards are nice.
Splinterlands is not unlike Poker once you get into it and see the same opponents every now and then!
I tend to rely on Bittrex as my main exchange, works fine!
There are two areas of blockchain/Hive that I'm not sure about in terms of ethics and etiquette.
Should I separate out some of my activities rather than have quite a diverse range of things on just the one account? My posts will range from gaming video let's plays, to beekeeping, to writing, to photography, to personal development, to fitness, to sociology, to game development, to business and marketing, to short narrative video and film, to medieval literature and history, to RPGs, to science fiction, to daily blogging and vlogging like a diary... etc. I'm still figuring out what the consequences might be of putting everything out on this account or separating some interests into separate accounts (business and finance; game dev and gaming and RPG; sociology and culture; personal development and daily blogging/vlogging). and then, is it OK to reblog content from one of my accounts on another account if I think it's relevant? Or would that just look like self-promotion rather than careful curation?
Then, there's how I use content. Is there an unwritten expectation about say, if I post a let's play series of me playing Minecraft on 3Speak, and then also uploading the same video series to a YouTube account? Past experience tells me to upload to any and all platforms however I wish; it's my content after all. But it seems a bit strange to say, upload the same content to 3Speak and Dtube etc.
How other people use their multiple accounts, and how other people use their content across multiple platforms, is something I'm interested in finding out more about. Seeing examples of it might help me figure out what I am happy with I guess.
Personally I tend to post along the same themes with my main account and I use alts for selfies and actifit.
You can always just post within specific communities with your main account, different topics.
As to posting on multiple platforms, I don't with blogs but when it comes to videos, which I only do very occassionaly, I might use YouTube - I don't think it's an ethical no go zone to post on multiple platforms!
