What's unfriendly about the following command?
\cite{some_book}
The fact that if I typo it to \cite{some_booky} it doesn't compile. And unless I rigorously recompile after every edit, I might not even catch that. Worse if the brace is missing.
What's unfriendly about the following entry?
It's in a separate file, for starters.
Also, you need to run Latex *twice* to get it working properly (the first time generates the .aux and then you can do it again). Oh right, creating a makefile is apparently easy for everyone.
And like I said, if you forget a comma at the end of the line, it doesn't work.
Oh, I guess I could just use readily-made citations that I can copypaste in from ieeexplore and the like? Well, guess what, the readily available bibtex exports are crap. For example, the bibtex containing all RFC:s (http://tm.uka.de/~bless/bibrfcindex.html) have all sorts of stuff in them that shouldn't be included (including standardization status and what RFC's it obsoletes). When I wrote my latest paper to Elsevier that included lots of RFC references, I basically had to run that .bib through a bunch of perl scripts with lots of regexps to get rid of all the cruft. Same has happened with most other readily made citations. At least the Word's XML has enough of the damn fields that you can pick'n'choose what to include in the reference. With bibtex, I have basically resorted to turning everything into @MISC.
So easy....not.
Only problem I have with Word's citation mechanism is that there isn't an easy way to get citations directly that format, but I have been using Bibutils (from http://sourceforge.net/p/bibutils/home/Bibutils/ ) to get back'n'forth between various formats.
I'll give Latex that it produces the most neatest documents there are, but to get that far you end up fighting all sorts of indicate details far too much. Don't even get started on how to create a new document class - if your text doesn't quite work with any of the provided classes and you'd like to create your own styles, good luck.
