I use quotes frequently, and sometimes nested quotes or multi-quotes, but do find that over-use of nested quotes is quite annoying to read, and in itself diminishes the response.
Personally I like the grey background for quotes, It makes them pop out as being "important" to the topic, and provides contrast between the quoted text and the current post.
That is, unless the person posting is too lazy, and puts their comments within the quoted text.
However, on a similar note, I initially found the grey background for indented text to be annoying.
Since that change was made, I started using it as a kind of mini-quote (and a quotable quote). But, in a sense, normal background would be preferable. One thing, however, as my eyeballs get older, I dislike low-contrast text. So, grey text on a grey background???
Another annoyance I noted a while ago. Lists no longer have the bullets indented. I think it used to be that way, but I noticed the lack of the indent a few months ago.
Did we ever get tables back?
[table][TR][TD]abc[/TD][TD]def[/TD][/TR]
[TR][TD]ABC[/TD][TD]DEF[/TD][/TR]
[/table]
Any chance of ever getting superscripts and subscripts?
CO[SUB]2[/SUB]
X[SUP]2[/SUP]
LaTeX?
[tex]\sum\limits_{i=1**^n {3i**[/tex]
Grrr.... something killed off my LaTeX (which I think I wrote a while ago, then borrowed from another website).
