Bringing together a community has become very important these days. Simpley because ,in a community you might have a lot of like minded people and others expressions might be important to others.But asking everyone to write at one place can not be always possible.The planetplanet offers a wonderful yet very very simple solution. The rss aggregator with a templating engine.
What planet does it ,it simple fetches all the contents or feeds from various blogs (All blogs do have a rss feed basically a simple XML file with predefined or globaly used tags ,so that it can be easy to parse) .and when the content is fetched just use a simle html template generator,and put it on to the web .A solution that i applied to my institute wherein we fetch all the blogs by students and it provides an amazing read to look what our own friends have to say about things happening in and around us. Same solution can be applied to projects especially when they are colobarated over the internet.Where all the developers blog can be read at one single place and it does not take much space too ,as the engine does not save pages or images it simples keeps them in static html file overwritten everytime a feed is fetched.
Linux Desktop Testing Project (LDTP) a project that i have been working with for 4 months now uses planet to read all developers blog ,given we have people from china too. you can check them at ldtp planet .
Unfortunately it doesnt come with a installation manual on the web although they have put in a READ ME in download directory .
Although you can check out a installation READ ME here
