I've got a tricky SEO problem.
brk: I'm not sure that it deeply matters in your case.For the most part, there is no SEO magic that can override valuable/new/insightful content in the long-run.Run your blogs as you normally would.  People who like them will link to each one respectively.  They will get mentions on Twitter.  They will get indexed appropriately.Unless you are in some highly-competitive keyword space it probably won't really matter much in the end.
