I've still to look at it. There is room for news but not lots of it. I think it neeRAB to be linked to your blog. So lets say you see something about about Paramount trying to resurrect Star Trek as a TV series again. You post that in the news section then put you opinion/thoughts about it in your blog.
Equally with reviews. Have one as a general review this is the story and what happens, a kind of stnopsis. Then in the blog you go into details about it as to what works, didn't, your likes, hates and general rants f you have them.
It may help to keep it from being random postings.
I know a guy that loves wrestling and wrote his own blogs, reviews and news etc. It was all very well written but it's biggest failing was it was too much. He tried to cover everything and always be up to date. This resulted in two problems. Firstly it was wordy. Very very wordy to the point it went on and on and was boring to read. You had to devote at least an hour to read it all each time the second and possibly a bigger problem was his postings were erratic. because he wanted it so full, so perfect and si current he wouldn't post on a regular basis. Sme times it was a Friday. Sometimes a Tuesday or a Wednesday. Sometimes once a week, sometimes two. Sometimes he would miss a week or it could be three weeks between postings.
The downside of that is people get fed up keeping going to check for updates or second guessing when the next one would be. Just because he said next one is friday didn't mean it was.
IMO it will help if you have set days whether weekly, fortnightly or monthly that you will post so you get a routine. If you end up doing extrs thats fine they'll see thats when they go on the next proposed date. It's the advertised one that creates the routine of going to your site regularly.
