There can't be two opinions regarding the addition of blogging features to sajha but I agree with paramendra regarding the way it should be integrated with sajha. Reinventing the wheel is just a waste of time. Each user has his own preferences regarding the designs, functionalities offered by a blogging site and there already exists a lot of sites answering to various needs of bloggers. So, IMO, sajha should rely on the RSS feeds of external blog sites ( of Sajha users ) and present its blog portal in a way which is convenient for other sajha users to browse. ( A good example is google personal page (http://www.google.com/ig) which creates a convenient personalized page for its users by getting info. out of the RSS feeds of popular web portals and those registered by the user)
