Does publishing on Leofinance.io not make the article appear on other Hive interfaces?

Of course not! It will appear on all hive interfaces!

But now here's where things get interesting.

Here's the code from my most recent post, posted from leofinance, as viewed from hive.blog

<link rel="canonical" href="https://leofinance.io/@trumpman/commie-andrew-yang-shills-bat" data-reactid="5"/><meta name="description" 

And here's from yours

<link rel="canonical" href="https://peakd.com/hive-175254/@culgin/the-290-gap-is-filled-where-are-equities-headed-next" 

Now, I am not much of an html coder but I think that little piece tells the google bot where your content was supposedly originally posted. Also, when posting from leointerface, it will also automatically insert a link pointing to your article in leofinance, which further helps the google crawl bot make its decision.

Btw, I am not trying to force you to use leointerface, just pointing that since you have a respectable amount of leo (and also earn much from your posts) it makes more sense to use it if you want them to worth more money in the future. Like i do. Hopefully the leointerface will one day be as good as peakd :D
