I have only just started my blog and I write about a number of diferent topics, posting previously published articles and posts about my travels, with photos. I am also planning to do reviews of books I have read and liked.
I have found that people who like my writing read my blog too. I sometimes write about my experiences as a writer ('My e-book Experience', for example) but I try not to rant or complain. My blog is getting an increasing number of views and I think it's because of the variety of topics. I try to have something new about once a week or so.
