We’ve usually don’t some in-line text in bold face. Unfortunately you could miss one skimming the paper. Color would be better, but it doesn’t always print, and I tend to proofread printed copies. Putting the comments in the margins was nice, because it didn’t change the layout or pagecount, and it’s really easy to skim to see if there are any left in the document.

Changing the font color inline (with an appropriately named macro like “todo”) is what I ended up doing for my CSCI Senior Seminar paper. That said, this is probably a better way of doing things. While this information would have been more useful to me when I was doing my senior sem, and I may never touch LaTeX again, this is still a good find and nice to know.
