nothing

Umm... try talking about anything interesting that happened (it can be today or something you can remember)? I am also stumped as to what to write on a blog.

Well, it can be difficult to get a general idea what you want to write about.

Me for example, I'm a geek, nerd - what ever - and as such I write mainly about stuff within that sphere, focused mainly on the SQL langauge, other technology aspects and the occasional general musing (some of which I double post with this place). So many blog about their main interest, whether be profession or hobby and whether it is gardening or painting or - like me technical.
Others prefer to keep a more personal approach and write about their experiences almost making their blog more a diary for friends/family to keep in touch via, others again are mainly news reporting and commenting, putting their spin on current events.
