What do you refer to as 'main Hive'. Ecency.com is one of the main browsers for Hive content, along with Peakd,com. Not sure how many users are still using hive-blog, i guess that could be referred to as the main site. There's also a bunch of 'outposts' where you can view content under certain tags, like sloth.buzz for #slothbuzz content, or hiveme.me for #MEME etc
