Missing the occasional definite article out is something that seems to be fairly common with second language english speakers.

I decided some time ago that it was worthwhile forcing myself to adjust until it wasn't noticeably painful; there are too many people out there I want to communicate with who do it.

Agreed, people all over the world are going out of their way to post in English so we don't have to constantly go to a translator. If you really do not understand what is being said ask for clarification, otherwise just be appreciative.

Spot on. ESL. Grew up in the U.S as a kid. Took grammar as elective. But I can't perfect my writing (and am too tired to correct it now). Shoot an email to yeukhon@acm.org for a correction, if needed. Just fixed a bit, not sure if the revision is better or worse. Probably missing some "the". Can't edit it now :3
