Karma – great first post & I love your style.
Good topic too – I’ve just started a tumblr blog having been wanting to blog *something/anything* for ages but don’t have the time to write lengthy well thought out pieces on one topic. Tumblr appealed because of the variety of post formats, ease of posting, etc.
I’ve found that it’s worth taking a bit of time playing with some of the formats and options, to see what works best for me, and it’s been enjoyable so far.
As you say, I can also start several different blogs /easily/ so I can comfortably post on my widely-different areas of interest with ease.
Hope to hear more from you @40Tech!
