Some people have asked me whats the real difference between blog posts and articles.
Blog posts are date centric, meaning there is no criteria other than the date (down to the second) which makes a blog post unique. Any blog post can have the same name as any other. The reasons behind that are blog posts tend to be much more prolific than articles. If a blog post today has the same name as a blog post from two years ago, who cares. Blog posts are also very static, once a post is made it should remain as is.
Articles on the other hand are dynamic. They are changed from time to time based on new or changing information. This means they are name centric. There can be no articles of duplicate names, the name of the article should remain unchanged, and explain what the article is about.
Even though articles and blog posts use the same wiki text markup language to format the posts they do not interfere with each other. Blog posts of the same name as articles have no problems.
Sparce links has been updated to the lasted version. It now uses del.icio.us to populate its links, which pretty much now makes it a UI for del.icio.us. All that's left to do is keeping persistant information about link to count clicks so the links can be ordered by most used.
So you wouldn't think this site would have a problem with comment spam since it gets so few visiters, but over a given week I get about 100 spam posts in the comments. I've added images for authentication to comments so in order to make a comment you have to type the text you see in the image.
I continue to expand the code for indeepthought and have implemented more of wikimarkup. If your curious about wiki markup you can see two competing standards here and here. Which one am I using? Neither really, there are parts of both I don't like and since neither is an excepted standard by the community of wiki I am basically using my own derived form based off wikipedia itself.
