comment amsmath: When to use `equation` environment instead of `align`?
the reason for not using the align environment is not just to make barbara happy. the internal processing is different for equation and align. i will try to come up with an example that will show the difference visually, not just by examining a trace of the process.

comment frame more than 1 equation (but not all) of an align environment
a "counter measure" that might work is to figure out what is the widest left-hand-side element, and force one other left-hand-side element (in the boxed or not-boxed portion(s)) to that same width. not elegant, but the easiest workaround i can think of.

if you look closely, you will see that the equals signs are not aligned between the boxed and not-boxed groups. unfortunately, i don't know the answer -- but it's a good question.

comment Loss of greek symbols in epstopdf conversion
My first guess is that the greek font isn't embedded in the eps file. but i'm not sure how to check that.

comment Is there a LaTeX wrapper for use in Google Docs?
to make this answer longer, you might quote the text that accompanies the latex link on the page you cite. although it's true that some (very useful) links go dead, my impression of this one is that it's in much the same league as the sites in @henrimenke's answer.

comment How to create new font which is thicker version of Computer Modern
in your last sentence, you say "doable with pdflatex". to me that simplies that the fonts could be made with pdflatex, so i think you really mean "usable".

comment How to create new font which is thicker version of Computer Modern
@Sverre -- as far as i know, multiple sizes of concrete exist only in metafont form. there are some vector (type 1) versions for vietnamese on ctan in only some sizes. the original question seems to me to be looking for a font to be used in text as well as math, so multiple sizes would definitely be desirable. (the typesetter knuth used for concrete mathematics used metafonts tuned to the exact pixel resolution; vector fonts weren't needed.)

comment How to create new font which is thicker version of Computer Modern
"computer concrete" is indeed darker than computer modern, but there are other differences too -- it's essentially an "egyptian", or square-serif font -- so while there are strong similarities with computer modern, it's really not at all the same. an article by knuth, "typesetting concrete mathematics" was set in concrete roman, and should give a reasonable basis for comparison (even though the on-line copy has been scanned).

comment LaTeX amsthm package - starting the 'section' number at 16
setting the counter (as in the answer) is correct, but if you are starting on chapter 16, it seems that you should be using the [chapter] counter as the theorem option. (confused? so am i.)

comment Referencing within an align
you don't need gather; in this context, equation would be better. (aligned would also work as an alternative to split.)
