Reactor microblogging engine

It all started with the fact that we decided to make our microblogging service. Rummaged on the Internet in search of more or less suitable ready microblogging engine, really did not find anything. Then we considered the candidacy of the engines of regular blogging - Wordpress , LiveStreet , BigStreet . We have already worked a little with them, and decided not to use in view of their architectural flaws (our IMHO). It remained to do something different, but not from scratch, but using the symfony framework in conjunction with ORM Doctrine.

We will be brief.
# What is it? - Microblogging engine with pictures and moods, alpha version. An example of the engine - http://joyreactor.ru/

# Our goal - Looking forward to hearing feedback. Perhaps someone will come in handy!
