I experimented with gensim's implementation of doc2vec this year; despite not being able to achieve similar results in sentiment analysis (because unshuffled datasets in the original paper) it's still really impressive. I analysed some document relations in wikipedia, and it finds some really unusual / neat relationships, e.g. Autism - Cat + Dog ~= ADHD.

That relationship makes so much sense to me in the form Dog - ADHD ~= Cat - Autism. Brilliant!
