[R] Tone in mailing lists (was " issue with "strange" characters (readHTMLTable)")

I did read How To Ask Questions The Smart Way <http://www.catb.org/%7Eesr/faqs/smart-questions.html> and I don't have a problem with calling me stupid and/or a winer for posting this...

What's the purpose of an R Mailing list (especially r-help), after all? IMHO it should be about R users being able to ask questions and getting help from those who would like to provide some. Unless a post has been written in an clearly offensive tone and/or shows a major amount of ignorance on the part of the person asking, why would you want to not just provide an answer to the question posed but deliver on top either sarcasm, personal criticism, sharp remarks or the like?

I also believe that it's in the nature of things that R users will most likely rather post about problems/bugs they encountered than to simply drop a line of acknowledgment for the people who continuously develop R and its packages. It's nice if they do explicitly express their gratitude in their posts (and this *does* happen a lot also), but it is not *demanded* and if they don't, it doesn't automatically mean that they are not grateful...

Please understand me right: all the people working on pushing R forward do fantastic work and I greatly appreciate the inputs from the entire community, I sometimes just wonder about the tone in the mailing lists. But that's probably just me , maybe it's just the way the cookie crumbles in technical mailing lists ...

Regards,
Janko
