They lack description in docs listing, although they have that fancy colons showing that description should be right there. Looks both confusing and unproffessional, should be fixed quick, especially that they are very important docs. Thanks in advance for doing that.
Do they really need an abstract? Their titles are self-explanatory IMO.
For me they look terrible at page where every doc has description, and many other guides have even more self-explanatory titles (The X Server Configuration HOWTO, Using UTF-8 with Gentoo, Gentoo Printing Guide, ...). Sorry, my vote still goes for fixing it. :)
/me agrees with rane
I agree too. A couple of lines really doesn't hurt.
Fixed (apart from philosophy who already had one)
