I mean, I understand what do you mean bean a Spanish speaker first, yet I do comment on Spanish channels, however English is the first language for many and the most spoken language as a second language for most of the world.
But I think your goal wouldn't only be notice by whales, but by the community itself, but that is just my opinion.
However if you make the choose you should invest more of your time correcting your English and learning more.
If you are facing some difficulties check my post about learning a new language, https://steemit.com/languages/@siragrays/language-learning-difficulties-1-part-1
I would rather use English, as well I would like to write in other languages when I feel confident with my language ability in those languages.

I saw your post before.
It's not a matter for investing time/money into learning English . The matter is very free platform Steemit enforces to use/learn English or to die.
Try to imagine how your time/posts/following would be changed if every post would have Translate button and simple autocorrection or grammar checking?
I see, the fact that Steemit is a platform for everybody is makes other languages users a little hard when expressing their ideas English, tho Steemit is pretty young. That could be a cool extension or tagged, And even Useful.
