Right now I have no (convenient) way of editing or removing posts... (As in via the web interface...)
In one way I like that: it makes me forced to live with mistakes I make. However, on the other hand, I would also like to correct myself. Although that is very doable by just sending a new post...
I also have plans to implement perma-links to posts, which means that I would be able to more easily reference other posts.
I should also paginate posts. I don't think it is a great idea to serve one hundred posts on the homepage, once I inevitably get to that amount... Also searching for posts would be nice... It is somewhat easy to implement, it would just take time...
