My understanding is that Hunting means a new tool that you've found. Some people Hunt lots of tools that they think are cool and people need to see. Others have developed these tools themselves and want to Hunt it to tell people about it.
Hunting is just another word for distribution. @sarvpriy_arya The idea is most Product Makers create their PH account few days prior to the launch. In that scenario they hardly get any support from PH community on their own. So a hunter introduces this new product to his or her PH community and helps the maker get that initial boost.
"Hunting" for a product typically involves actively searching for, uncovering, or introducing a new product. This term is frequently employed in the startup and technology sectors, notably on platforms such as Product Hunt, where users showcase and discover new products.
