okay, i’ll contribute.
i don’t know much, but did talk with companies about writing for them. my info may not be the most accurate, but companies are looking for full-time people these days and from what i’m told, the job isn’t easy and may really fill up your time. it involves first getting a hang of the software that you’re writing for, then presenting the “how-to” in the most easy-to-understand fashion. many foreigners used to write part time. but from what i heard through interviews, part-timers screw up the whole process cycle e.g. the programers need to talk to you on an ongoing basis etc.
i think part-time is the way to go, if you can get one of such.
any other opinions?
