I run my own blog & use social media to connect and promote it but am I making work for myself?

[Stuart]

I run a blog in which I promote and review historical fiction novels as well as promote my own writing and interview authors and bloggers who are just as passionate about HF as I am.

I use Blogspot, have a dedicated FB page, a Twitter feed, G+ and have recently joined Triberr. To automate some posts I have found Tricklr useful. My question is am I able to increase my social media output, either by using alternative platforms or by automating some tasks?

I know a bit about SEO and am learning new things each day as I would love to make my blog (and it's content) the very best it can be. If anyone has any ideas or tips I'd be really grateful.

Oh, and just out of interest, if you want to look at my blog it can be found here:
