There are a number of sites that attempt to catalogue the most popular weblogs overall, based on inward links (I have catalogued the ones I know of here: http://www.netvouz.com/davidbrake?tags=weblog +search) but none that I know of that let you know the most popular on a given topic or keyword over time (you can use some to search for a keyword then show you the top-ranked blogs within that but that again favours the most popular overall not the most popular within a given subject domain). I would also be interested in a search engine that could tell you which blogs are the most popular in a given country or region - or better still an engine that does both, telling you which blogs are, for example, the most popular blogs about the Iraq war based in the UK. I don't suppose there are any search engines that let you search by the (expressed or inferred) demographics of the poster either. If anyone knows of a specialist search engine which does any of the above could you let me know? (And if any of you have the ear of one of the search engine providers could you encourage them to provide these tools?) --- David Brake, Doctoral Student in Media and Communications, London School of Economics & Political Science <http://www.lse.ac.uk/collections/media@lse/study/ mPhilPhDMediaAndCommunications.htm> Also see http://davidbrake.org/ (home page), http://blog.org/ (personal weblog) and http://get.to/lseblog (academic groupblog) Author of Dealing With E-Mail - <http://davidbrake.org/ dealingwithemail/> callto://DavidBrake (Skype.com's Instant Messenger and net phone)
