Do You Use Tumblr.com?

Hi Friends,
I was introduced to Tumblr about a year ago and thought this is just NOT for me.  I have my blog and I bookmark my pages.  I really just kind of forgot about it until about a month ago when it surfaced again with a number of both crafty women and on the problogging circut.  Tumblr promotes itself as being a great place to use for "Social Bookmarking things from the web".  I looked at it again and decided to give it a whirl.  It's not like blogging as you can't leave comments on other posts unless you change some HTML code.  I had a hard time figuring out how to tag my items so I could retrieve them later but I think I have that solved.  Anyway, I call it my "Happy Place of Inspiration."  Over this past month as I've run across posts that make me smile or inspire me in some way I've placed them in my Tumblr with links back to the original page to find the tutorial or recipe etc.  Anyway, it has been kind of cool.  I'm not looking for Tumblr followers here, but you can look at my page just to see what it is like if you want.  Here is my Tumblr page:  http://basketmastercreates.tumblr.com/ 
For those of you who use it, I know there must be a way to archive posts month by month because I've seen it done.  Perhaps you could direct me as to how to do this.
What my Tumblr pages remind me of is a wonderful magazine to sit down and flip through.  I love reading a good magazine with lovely photos and I feel like I have my very own personalized magazine here.
Baskets of Happiness Everyone.
