I discovered an increasing trend of Blog Aggregators ( Blog Lists have been around for a long time). Several sites come in this category- http://bigdatanews.com/ (which is a GreenPlum /AsterData sponsored site on Big Data) , http://mapreduce.org/ (which is a site on MapReduce that has an inbuilt blog aggregator but is more of a community website – I will explain the difference below) , http://www.r-bloggers.com/ (which is an excellent aggregation of 69 R Bloggers sites that is built by Tal and is currently not sponsored/independent) and http://smartdatacollective.com/ which is sponsored by Teradata and uses http://wordframe.com which is a paid software) and some others like http://www.biblogs.com/ (which is Adsense supported :) ) and http://javablogs.com/Welcome.jspa (an aggregator on Java) (or even http://feministblogs.org/).
CMS Based Blog Aggregator

I am noting blog aggregator as a distinct website that pulls in automated content from RSS feeds , may or maynot be moderated, and usually revolves around a certain domain or topic. It is slightly different from community websites which have Lists of Blogs as part of many other features, and boutique collection of blogs like http://www.b-eye-network.com/blogs/index.php
and Intelligent Enterprise ( http://intelligent-enterprise.informationweek.com/blog/index.jhtml) as they have selected authors and have more than Blogs as their featured content including News etc. Since community is a buzz word- many websites claim to be community websites while retaining the look and feel of a CMS- Blog Aggregator.
WordPress Enabled Blog Aggregator
Anyways, if you have a WordPress Installation- you can create a Blog Aggregator for free. Basically there is a wordpress-plugin called FeedWordPress http://wordpress.org/extend/plugins/feedwordpress/
Doing so you can simply addin as many RSS feeds as you like –
(see a screenshot below).
Of course – you can use Twitterfeed to create a Twitter Aggregator/ Fire Hose that simply pulls in Post Titles, and can link them using Facebook-LinkedIn-Twitter apps to your RSS feed of the aggregated website. :)
Building a website /content aggregator is just a few clicks away and free for anyone with a website and some passion for a topic. It is really free and painless :)
