Good point and it's a potential trap of tools built from developers for developers.
There's this fine line between finding it useful and being willing to pay for it. Being honest to my self: Do I find this useful ? Yes Makes my web scraping easier? Yes Would I pay for it? Maybe... but the problem is I've never paid for a scraping tool either.
But other people may pay for it. To get to that point though I'll probably need a few more hands on deck, who need salaries and for that you need external funds.
