I'm still deciding whether to commit to a blog. For me it is a key question of time commitment and dedication.
The key factor that holds me back is I guess the community aspect of a forum that is partially lost on a blog, since the focus is on individual thoughts, whereas a forum is oriented around discussion.
Of course some of my favourite blogs do have a community associated with them, but chances are I'm not going to have one centred around my blog. A public blog can often be an expression of identity and some of the reasons for wanting one's blog to be popular may merely be due to vanity.
But there are many motivations and reasons for having a blog, the most obvious being the same reasons as a traditional personal journal (although one that happens to be publicly viewable).
I know a number of members here do have blogs, which they dedicate varying amounts of time to. Along with Twitter, I know Tumblr has had a rise in popularity due to recent trends in smart phone use. But the type of communication in those mediums is different to that of a traditional blog.
What are your thoughts in terms of the relative merits and time commitments?
How much of your time do you spend reading or writing blogs as opposed to forum participation? Do you see this changing in the future?
