To know who’s writing you can trust.
A website where people can submit a vote for or against a blogger and all relevant votes are aggregated into a leaders and losers list, changing regularly. You can also see the bloggers history over time. Every vote should be based on real experience and knowledge, and part of the vote submission process is writing a detailed reason for the vote. Each vote is only used if an editor accepts it. A voter can choose to remain private or not.
You see from time to time a remark or suggestion made by a friend on Facebook about a movie they saw or an exhibition they visited. Wouldn’t it be good to have a place where you can see all your friends opinions and ratings of experiences they had?
A Facebook app that lets anyone rate an experience and aggregates all that are in your network. This way you can look up a movie and see who had what opinion and what is the majority trend.
Express your feelings and opinions about websites. Get to know what others think.
An independent website where anyone can vote up or down any website. Vote on websites already listed or add a new one.
People can share their good (or bad) book summaries so others can skip reading the whole book and get the gist of it (if the summary is comprehensive enough.) Readers can also get a better insight and help them decide whether to read the whole book.
Have a site where people can submit their summaries for new books or even books that already have other summaries. Use a rating system to give priority to users who’s summaries are better.
