Okay. I don't recall asking people to "prep for wordpress" by leaving spaces. If one wants to prep for the wordpress blog, it would be much better to surround math text by something like \( \) where there's a distinction between the left symbol and the right symbol... since then I can use a global search-and-replace to convert \( to `$latex ` and \) to `$`.
It's a real defect in old TeX that there's no visible distinction between a "left dollar sign" and a "right dollar sign". Knuth, as a computer scientist, should have known that a language where left and right parentheses were the same would be very bad!
