Tumblr vs. a Social Network

I have profiles on facebook, linkedin, and a few other social networks.  I spend almost no time on any of them.  I am starting to see my tumblr as my social profile rather than my blog. 

Facebook and the like serve a purpose to keep me in touch with friends, find out what they are doing, and letting others know what I am up to.  I do this through a series of wall posts, personal messages, friending, groups, etc…

While this is good for others wanting to get in touch with me, it creates a lot more work on my end to get in touch with them.  I would much rather just ‘follow’ them on tumblr and have their updates added to my dashboard feed.  Others could do the same with thegetdownguy.  I’ll reblog interesting things my friends/people I follow post etc…

Obviously this is not apples to apples, but the way I want to interact with people online is better served through Tumblr  than a traditional social network. 

I want people to have comments on Tumblr though.  I added Disqus to my blog, hopefuly Tumblr will have an internal solution soon.
