You already have some independent ranking services for business entities, but what about people?
A place where you can rate a public figure (a business person, a guru, a coach, etc.) as either trustworthy or not. You can also write a review. The individuals reviewed can also comment. Others can search for a person they want to check on and see their ratings. Only people with personal experience with the ones they rate can rate them, and their rating is not used or published until that is verified.
There are many benefits to being a member instead of buying. Some are personal access, no substantial upfront cost, always updated, quit anytime, etc. Having a members club is also beneficial for other reasons. For example stable income, attentive audience, etc. there is, however, one problematic facet to having one: you need to keep members interested so they won’t leave.
Build a membership plan that has only one component: you. Give the group access to you in the form of a weekly or monthly interactive (online or offline) group meeting, where you talk a little about your relevant experiences of the past week or month, and then anyone can ask questions, and you answer them. You should also close the meeting with a cliffhanger for the next one, and deliver the one you promised in the previous session. That’s it, nothing else. No Extra content, no new training, etc. just a periodic access to you and your brain.
You would like to process your emails quickly by reading a single sentence or a very short paragraph.
A software or a service that synopsizes your emails for you so you can go through them quickly.
You are more likely to take notice if the ad is calling out to you and your specific needs and wants.
Recognize the driver (by the car’s license plate, his mobile phone’s position, etc.) and display a personalized ad on the billboard.
You read something and read it again, go back and reread it, you have some trouble understanding it, or maybe you have some thoughts you want to pursue.
A smart reader (browser extension, e-book function, etc.) that suggests more information based on your behavior while reading. For instance, if you read at a certain pace, and you stay longer on a paragraph, you might get a pop up asking if you need to dig deeper into details or would like to expand by getting related information.
