Purpose of a blog

I'm having a hard time deciding what to do - I have a couple of domain's still and a hosting service (holeinthewallhosting.com). Currently, I have my old "company" domain, elitepixel.com which is now pointing  back to my old tumblr blog; I really liked posterous, and had changed everything over there - but then it closed shop.

When I heard about it closing, my brother and I started searching for the alternatives that would provide a similar experience (basically, being a blog). I demo'd WordPress  blogger, tumblr, and the roll your own types... my brother decided on WordPress . I was going to go with him on that, until we found out that you have to pay yearly just to have a domain pointing to your blog... I already pay several annual fees relating to my online stuff, so I chose not to go that route.

I love the ease of posting stuff to tumblr from my phone, pc, or email; however, since returning to it, it seems overly sluggish no matter where I access it from, different networks, cellular, lan, wifi, public, private - it all seems the same to me: slow. I've currently set my elitepixel.com address to it, but am thinking of just coming back to blogger due to the integration of google products. Plus, I can use g+ comments where on tumblr i have to set up disqus or something like that... #pain

That leads me to a question of usefulness... There are certain "blogs" that I think should exist, but I'm thinking my blog shouldn't. The only thing I really use it for is to post pictures, video's, and links that I want to share with friends and family... don't we have g+ & Facebook for that? I mean honestly, no blog I ever create is going to have a bigger or better audience than that of any social networks I use.

I think I'll add a pointer to my g+ profile page under my domain name(s) until they expire - but I don't think I'll be renewing them. I just paid for a pro account for flickr to store the original photos I take (mainly so I can backup all my photo's at their original size - flickr is the cheapest option for that at only $25/year). So I'd rather cancel my hosting and utilize other free tools to reach the people I'd like to... I just don't see a reason to keep them. Any programming/playing around I do is no longer web related, so I don't need a sandbox, playground or platform for any of it.

I honestly think this applies to just about everyone, at least when talking about individuals and blogs - things like lifehacker, makeuseof, gizmodo, etc, I think still need their blogs - but that's more of a platform than a blog and I enjoy those as more of "news" feeds... even if you like limiting your audience on your blog, you can limit and have more control over who sees your posts on both Facebook and (especially) G+.

So in the hypocritical way of self-importance and such, I wanted to post a blog post about blog posts that are really unnecessary now that we have networks that have rendered blog posts obsolete.
