You can add your comment there to lend further support.
There are other Latex generators - I use codecogs - they look good for standalone equations but are misaligned when used inline.
I'll check out that post and give my input.
Codecogs looks good as it has clickable symbol icons. I sometimes forget code for certain symbols. I'll keep it in mind along with QuickLaTeX.
