Following this forum and SimplyDiscus.
Selling is hard. Anymore, its quicker and more rewarding to just give stuff away. On Sunday, I took the contents of a 5gallon mini tank I have, 2 peacock gudeons, 1 otto, 1 amano shrimp, some dwarf vals and bulbitus, to an aquatic club meeting and donated it.
That said... I did get help here in the 'Looking For' section... Got some useful information on components and was able to purchase them.
The DIY sections are falling off on both sites. A decade ago you had allot of FishRoom threads. Hardly see those anymore. The hobby is cyclical and it's heading through the trough at the moment. It will rebound... and eventually crest as well again.
Forums are loosing in popularity because they are not as easy to use with a cell phone. I've been in contact with the NextDoor folks about modifying their software for use by private groups and clubs. It's a facebook like interface and could be a good bulletin board forum software alternative. They've written several times with promises to update me.. It's been a year of back and forth emails, so I don't think anyone is actually taking it seriously. I really think nowadays the forum software itself is an obstacle.... it needs to develop to be super easy to use via a cell phone and for posting photos.. It's just how this new generation works.
Facebook has 'forum' addons that can be added to a users Facebook Page (or are they still called walls?). You get the the benefits of facebook like blogging... but then the 'categorization' of a forum addon. I don't know if that's an alternative to attract people or not?
Personally, I prefer forums over facebook/instagram but I know that I am in the strict minority on that.
learning never stops...
