My area of research is math information retrieval. In particular, I come up with several basic ideas how to make use of a promising discussion platform offered by mathoverflow.net (MO). That's why I'd like to ask for opinion of professional mathematicians and users. Do they look helpful? What ideas do you have on your own?

- Integration of MO with an academic paper search engine, e.g. automatic retrieving citation links to relevant papers on arXiv. This might be a recommendation service for a given question, as well.
- Integration of MO with Wikipedia/Wolfram Functions Site (or similar resources). This can be done for enriching an user interface with widgets displaying useful definitions or basic facts about mentioned mathematical knowledge objects (terms, theorems etc.)

Thanks in advance!
