Is blogging a distraction or a help?

Spent a few days outside recently and not as much time spent in front of the PC.
Managed to get a little sunburned for my troubles!!

Now back in front of the screen, I'm wondering if blogging is really worthwhile?
I read lots of blogs of people from all over the world and have found a varying degree of interest.

Very quickly, so it seems, a couple of hours passby almost un-noticed and work which should have been completed has been set aside until later. (Not a good idea)!
After family, work comes first and trawling blogs is well down the pecking order, but without realising it, the blogs seem to be working there way up in importance instead of down!

I suppose we have to consider the benefits and in truth, there aren't many in favour of blogging for blogging sake, (like this one), but there are distinct advantages in blogging for business and advertising your wares completely free of charge! (yorkshirepropertynetwork.blogspot.com).

Either way, I'll keep on feeding the distraction for quite a while yet.
