So I made a Slender blog

You started it last night and you already have 4 posts? That's moving a little too fast. You need pacing. Unless you're planning to keep churning out posts at the same rate, it's going to seem very inconsistent. Then again, if you do post that much, people will probably get tired of having to catch up on that much at once. It's unmanagable for the reader.

Your first post alone was kind of a huge text wall. Maybe break it down into separate paragraphs for separate interests? Also, if you're going to write a blog, please write. There are a lot of run-on sentences and the intermittent "lol"s make it kind of difficult for me to connect.

By the end of the first entry it seemed pretty obvious that it was going to be a slenderblog. I think something that begins like "me me me me and now I'm going to give my opinions on slender man!" could work in a satire context, but it feels like it's lacking any kind of subtlety here. One of the best parts of a Slenderblog is letting the paranoia build up. Slendy is supposed to screw with your mind and make you think every shadow is out to get you.

Also,the character made the blog with the intended purpose of ranting about things. But now he's just using it as a personal blog? That doesn't make him seem very focused.

The words "suit "tie" and "DEATH" keep appearing in his dream? I'd be more worried about being taken out by the government than Slenderman if I kept seeing those.

The whole blog so far is really too in-your-face about it. Suddenly Slenderman all in one day? It's not believable, which is something that is important to this genre. I think if you're going to write a blog, you should really have read some of the others as a basis for comparison and to know what people expect from these things. I know the feeling of being eager to put out something for people to read, but quality control is a must. You need to make sure that it's something people want to read. Or else just be very secure in the story you want to tell, and not give a damn what anyone else thinks of it. But as it stands, it's got quite a lot of room for improvement.
