Revised, minor edits. Great start! =)

- Bolded speaker names at the beginning of the paragraph.
- Changed capitalization of things like Emacs, Perl, UNIX, Unicode, etc. to be more consistent
- Changed "mod" to "mode"
- Changed punctuation to make sentences shorter and more natural. Use periods instead of commas when things threaten to become run-on sentences.
