Agreed - I like fiverr over hiring direct because I don’t really want to be in someone’s rolodex as a customer they are going to call and pester. As for maids, I feel the problem there is you rarely get anyone who is going to do more than feather dust your home. So a “service” isn’t going to radically improve that. As for glasses I really want to like WP but their plastic frames really are subpar. It’s a far better experience to buy off the rack at Costco if cheap is what you’re seeking. For years I would spend $600/year buying zero G from a small boutique until I decided maybe instead I should have five pairs of WP... so I tried that and every single one of them had something I didn’t like.. so one day I found myself in Costco and decided to give that a go and have never looked back. Heh that’s probably indicator #641 I’m turning into an old fart.
There's really no way for them to stop it. It's all just about if they want to deal with invoicing and other stuff themselves or go direct. Many don't want to bother. But every wall they throw up makes it more likely people will jump off after that initial aquisition.
But many of these jobs ARE just one shots. Tho I usually go back to the same folks who did good work and communicated well with later tasks.
