Left wing think tank Compass also polled its members on whether tactical voting was a good idea last week. Its website includes a fact sheet on marginal seats.
Also discussing the issue were Liberal Democrats. see some recent posts on LibDem Voice.
On a more satirical note, famous political blogger Guido Fawkes has also been spolighting MPs who would lose their seats if voters employed tactical voting. Take a look at his blog for more.

For some academic analysis
see the CREST website. Centre for Research into Elections and Social Trends (CREST) is a Research Centre based jointly at the National Centre for Social Research (formerly SCPR) in London - Britain’s largest independent social research institute - and the Department of Sociology, University of Oxford. They have a number of papers on tactical voting. Paper 95
