Why don't people work on string field theory as much as they used too. It seemed the most natural and elegant formulation yet devised (and of course BI). Were the technical problems too hard to overcome?

An interesting toy model was discussed by Witten a while ago (hepth/9306122), and its ideology has been revived more recently (eg in hepth/0412139, hepth/0502211). In the latter an attempt was made to construct a wavefunction over the (moduli) space of compactifications, and morally speaking, this is what one wants to have: some measure for distinguishing between different background geometries, eg via the peaking of a wave function. All this seems in early stages, though.

Wow R.X.! That Schnabl paper looks fascinating! An analytic solution of the nonperturbative tachyon vacuum of Witten's threevertex model.

http://arxiv.org/cits/hepth/0511286 This is arxiv's list of 14 papers which have appeared subsequently and which have cited Martin Schnabl's November 2005 paper http://arxiv.org/abs/hepth/0511286 It is not bad for the first yearcitations include some by wellknown people: Douglas, Kachru, Trivedi, Washington Taylor, Zwiebach,...

Thanks for the list Marcos. I know I can always go to you for bibliographical help!
