The lacking topic

I seem to have a problem.- I want to write, but I am not quite sure as to what I want to write about. I read some stuff about writing a web logg (blog) and there seems to be about as many opinions about blogging as there are bloggers. What you should write about, what you must write about, what to avoid at all costs and how you are formulate your sentences are points which are very much not agreed upon, so I've decided that while I stretch my journal/log legs I'll try to dabble in various topics with no general heading. It's not like I actually expect anyone to read my blog at all - I simply toss my not-too-carefully formulated sentances out there in the void.
