What works well to start a real-life conversation does not necessarily make for good practice on an asynchronous forum like PerlMonks.

I completely agree with you. But respected opinions aside, it doesn't mean that someone, either intentionally or not, wouldn't display this behavior, even in a context and environment where it is ineffective or off-putting.

On the other hand, the OP did get a number of responses, some of them bordering on useful. So I would be inclined to admit a score of "minimal" success for the posts, while at the same time preferring a more direct exchange.
