Back in 2003, Gaia had more significant ties to the actual industry than it does now. Many artists would come here to chill, but also in a weird way network? Unintentionally, of course. In that way it was similar to Twitter-- it provided much needed exposure.
For example, Alex Ahad of Skull Girls fame got his start here. It's no coincidence that several old items have the Skull Girls art style, because he actually made those items. Jenzee was another artist, and now she's Super Giant's art director for Hades. VO (artist/dev) worked on Street Fighter comics. Another artist was Fayren Pickpocket, created popular items and characters like the Pale Marionette and Ringmaster Loyal, but now they're an animation director on Castlevania. And I think work on IDF's Transformers?
But... over time, there was a shift in direction, and Lanzer left thinking he was placing Gaia in good hands with an actual CEO. That CEO kind of... Promised too much to overseas investors that was not possible. Almost ruined the site. (Not to mention the politics at the time were hostile towards overseas investors.)
Lanzer returned a few years ago and purchased the site back, and that's when Gaia started getting its legs back. It's a slow process, and goodness knows the guy is trying. See: working with Ruffle and learning different programming languages.
However, trying to help the site he has made a few missteps with NFTs and AI. Thankfully, he actually listened to Gaia's user base and never implemented either of those.
That along with issues caused by the previous CEO, and another artist who plagiarized others (they are not on staff anymore), has made a majority of the art community rightfully cautious.
I think Gaia can start by offering actual tools to artists for portfolios-- like their own personal art gallery on their profile where artists can share outside of the forums. Or users who purchase art from others can display on their profile with links to those people. Place more focus on art contests again. Stuff like that.
