Years ago I joined Fiverr, I encountered other gig sites that looked and ran just like it. I remember joining one and then never getting a sale. Later in the site just close. Or, maybe Fiverr forced them to change the site or take it down. When I say it looked exactly like Fiverr, I'm not joking. the only difference was the site name/logo and some small changes otherwise. I remember other similar gig site coming out after Fiverr became popular, but I don't think most of them survived. What happened to them all? And are there any still out there worth working on?
