let me say it in 2 lines of text
reason = seo = google = pagerank = more visitors = better reputaion = better name = website
long text = normal for me = forum
now the explanation behind it or you wont be able to follow
short texts does not provide any seo or explanation
in my case , i love to write long texts and on my wesbites are those texts the main key to be able to find in google
how more text google can pick up that is relevant to your website , how more google will return and how faster you will get a pagerank
for that reason the index page got a bit of info on it that is relevant to the site ( a bit info of what it is) and the other pages not
for the users who know what it is is it to mutch info , for the users who do not know what it is then they can start reading
for the forum i got the same problem
as i am normal to type a lot of info into a text does it makes me automatic post big posts and not "spam posts" , also called Quality posts in some cases
they can be boring to read sometimes but mostly they are not that boring as i keep a structure in it to make it easyer to read
if you see your post and you see my post , then you see the difference and i am sure that my post is easyer to read as it is splitted up. but if i need to make a post this way like you make then then i totaly agree with you that i am to lazy to read the full text and try to understand what stands in there. but i guess that you are talking about the site or was you talking about my post i made in this forum ??
anyway , hopely this explained why my posts looks like this post
