Some of the good things: 

• Provides greater listing exposure to millions of consumers.
• The addition of tax records, school ratings, and other information to listings is good for consumers and makes the agents’ jobs easier.
• Levels the playing field for newer agents and agents without many listings.
• Gives consumer access to FSBOs, foreclosures, and other non-agent-represented properties, painting a fuller picture of the available market.
• Creates a new, broadly reaching, the advertising platform for agents to advertise their skills.

Some of the bad things : 

• A high percentage of their “available” listings are actually sold or off the market. This confuses and upsets consumers and makes agents look bad.
• The sites’ property valuations are often way off, making agents’ jobs harder.
• Promotes non-listing agents alongside listings that aren’t theirs, tricking consumers into believing they know the property.
• Sells to any agent, regardless of experience, the title of “Premier” or “Pro”.
• The “leads” generated for subscribing agents are low quality, non-responsive, and a waste of time.
• The cost of being a subscribing agent is too high for what you get.
