I have just downloaded Flock and am using it to write this post. I have only played with it for a few minutes but it looks like it is going to be a great piece of software. The blog posting feature is really nice. I wish you could change the font that the editor uses (maybe you can) because I really dislike Times New Roman. The browser has some other great features like publishing your favorites directly to de.li.cious, a history search using the open source search engine Clucene, RSS feed find, tagging of bookmarks, and a feature called The Shelf where you can drag URLs, pictures or text from any web page for saving so that you can blog about it later. This is a developer release but so far it seems pretty stable. You should definitely check it out.
I tried to publish to my blog using the tool but it did not work. I am using wordpress and that was not an option on the dropdown so it chose MetaWeblog. It successfully wrote to my blog but only I could see it under the admin section. Everytime I tried to view the real URL I got the 404 error. Hrmm
I have downloaded the latest build of flock and am trying the blog editor again. Let’s see how it goes.
