My understanding of BARK is as follows:
• It is a lead generating and selling business. There is no real guarantee the leads will be any good or even real.
• The consequence of Bark is to push down prices, as many suppliers compete for few buyers.
• Bark make money from selling leads, yet do not charge for the buyers posting jobs so there is an invitation for buyers to do market research on Bark, whilst sellers pay for this. There is no loss to buyers posting jobs to find out information, although Bark discourage this.
• There is no guarantee the suppliers will be any good.
• Debatable : For some trades, like plumbing or electrician or painter, where the service is a manual trade, albeit that skill and experience are involved, it may work ok.
For the creative industries, where there may well be a larger gap between the understanding of what is involved in producing the work, and the hopes and expectations of what work is delivered by the client, there is likely to be more disappointment due to ignorance, and it is less likely to provide good realistic leads, despite what Bark may try to have you believe.
• The HARM is may do in dashing your hopes and expectations, and you underselling and undervaluing your work may be much worse than not using Bark at all. If you keep getting disappointed by leads that were in any event only water testing leads and deliver great work at a much cheaper price that you would ordinarily get .... It may do you more harm than good.
• I am not actively pursuing leads on Bark any more.
