"It's always worth giving a shout out here in the Chatterbox ("Anybody using Frobnicate::Blorgle to process the widget?")."

This is good advice, as is asking "I found a few distributions on $name's MetaCPAN page, and am wondering if anyone has any experiences with that author.".

Often the author themselves may be here to answer any direct questions while the OP gets feedback from other users.

You could also contact the author directly to ask specific questions or to get a gauge of their responsiveness.
