should i stay or should i go?

i've been thinking about this little blog. where i started; how far it's come; what i've learned.

i'm debating on how to move forward.
do i continue on with BIHP and leave well enough alone?
do i delete some of the content that i don't really care for?
or do i completely start over, new name, new design, and all?

i've put in two solid years of blogging. i've "met" some really wonderful ladies. blogging has blessed me more than i could have anticipated. in all honesty, i want to start fresh. i have a new name picked out. and i lurrrve it. but all that time i put in to this blog, is that wasted? i know now exactly what i want to post, write, and share. so this is the crossroad i'm at.

i'm not worried about losing readership. and i'll save this blog and keep it up to remind me how far i've come. but i'm just not sure.
any opinions?
