> writing is hard and writing things regularly that people want to read is even harder.
For the second part, I don't write regularly. I don't look for an audience tuning in every Thursday evening. I write when I feel like I have something to write about; when I learned something new and interesting that I want to share, that more people should (or might want to) know about.
This gives me a URL I can share with friends and/or post on sites, instead of telling friends individually or writing a post on a gated community like Facebook. It gives me some of history on what I've been doing over the years, showing a potential employer I've been doing IT stuff out of school as well (very useful as a young professional). It even serves to remind myself now and then, e.g. my IPv6 post[1] I fairly regularly use to check stuff like "what was the maximum address length again".
In fact, not writing regularly might be more useful to many potential followers. If you only write now and then, they can follow you without fearing their inbox/feed will be flooded, and posts are much more likely to be of quality. When deciding whether to follow back, irregular or semi-regular Twitter users are much more likely to get one from me because they are usually more interesting and not a day to day burden.
