I think upvoted looks really sleek and I hope it is successful, but they really need a way to monetize and it is a really hard problem to solve. Obviously, using a widely supported mature CMS like wordpress makes it easy to produce content with minimal effort and cost but that has been reddit users largest gripe. Upvoted is a curator/aggregator built on top of a curator/aggregator, which is weird. Reddit's success and problems stem from providing the long tail of content, allowing diverse topics and communities to be covered while allowing globally popular things to float to the top. This means that there is rarely community consensus, so while upvoted has little risk as it is cheap to make, I can't see it providing much financial support for the company.
In all honesty though, I wish them the best of luck and hope to see them do cool and intersting things in the future. Obviously, improving the search would be a great start because Google is an awesome search engine, but for content discovery and curation, Reddit is doing a great job. Best of luck guys and sorry about the sarcastic comments about Wordpress and PHP, it really is a good way to quickly test out something like upvoted without significant dev reources and is a good content management system, edit: [if used correctly]
