The mobile revolution is shaking up the software market. Old paradigms (bigger is better) disappear and new ones are created.

One area where these changes are specifically noticeable is the relation between applications and the file system.

Most computing environments are in what I call the second generation, where the file system is the dominant part of this relation. The file is the centre of our activities. To start working we open a file and the associated application is automatically launched. We only start application directly when we want to create a new file.

This has not always been like this: in the past (first generation) the applications were the core, where applications gave access to data on the mainframe or in databases. There are some situations where we work in applications without having any idea of the underlying file- or database structure. E-mail is one of the uses of this system.

Like I said, the mobile revolution is changing this again. Mobile operating systems as iOS, Symbian and Android give very limited access to the file system and force us back to the mainframe era. Even the desktop operating systems don’t give you direct access to the file system anymore, but rather a virtual system mounted on top of the real file system.

It looks like file system abstraction is the future, but I don’t think that applications will be the centre of our universe. The operating system of the future won’t be centred on files or applications, but will use processes and tasks as the leading parameter.

In the operating system of the future, you will be able to say that you want to write, and a simple text editor will open. The moment you access more advanced editing functions, the application will automatically switch to another editing engine. Of course, you text is automatically saved and can be used in many ways.

In the future, operating systems will actually help you being productive. Trust me.

A recent trend in the blogosphere has been to add tweets as comments on posts. I understand where this comes from, as in general commenting on blog posts has decreased in favour of twittering. By adding all tweets mentioning your blog posts, your posts look more alive and will probably attract more readers.

Whenever I think about features for my blogs, I always ask myself what the value is for my readers. In the case of tweets as comments, I look for the answer based on my own experiences. It happens frequently that I find an interesting post with let’s say 20 comments. When I finished reading this, otherwise interesting, blog post and get ready for participating in the conversation, I find out that there actually are only two real comments, followed by a tweet of the author and 17 retweets adding absolutely nothing to the post or the conversation. Immediately my motivation to participate in the conversation is gone and I quickly move on to the next blog.

Although in theory tweets are comments about your posts (or at least mentioning the post), they hardly ever contribute to the discussion. If you absolutely want to display the tweets on your blog post, go ahead, but don’t mix them with the comments. If in the example above the tweets would have been separated from the comments and the blogs metadata would have shown me that the post has 2 comments and 18 tweets, I would not be so disappointed and probably would have left a comment as well.

A comment is a comment and a tweet is a tweet.
