The length isn't the issue. If that was it, then basically a lot of my posts would be problematic (since most of them typically tend to be very long). And with long posts, other viewers can just choose to read or not read the posts.
It's just that if others are interested in your posts (even if they're long), your last reply had no space between paragraphs (for each idea/points being made), and that itself is (like Game Bond said, no offense), very uncomfortable to read (I actually attempted to read your reply to me, but with everything bunched together without spaces between paragraphs not giving it room to breathe, it was giving me a headache & I had to give up after reading the third sentence).
I understand it might not be easy when you're in spirit of the moment, or when you're really excited about something, but still I'd recommend you to edit down your replies so they can be more concise (this is something I often have trouble with I think), and more comfortable to read.
