If your personal way of pursuing her is to make a blog and flood it with every picture you have, then so be it. It's entirely up to you to explore your faith as you see fit, and I would think no less of you for it. More, even.
I don't agree with it, though, I'm afraid... I don't really know anything about what this tumblr thing is, nor have I ever held an account for it or whatever they're called, but the knowledge I've gained by osmosis tells me that it relies on continual recycling and regurgitation of the same (cliche and tired) material (ad infinitum) through different people's pages; feel free to correct me if I'm wrong. In all honesty, that just sounds devaluing of something that I hold very dear.
What's more, I think that if someone who had just come across this place were to find all her pictures in one go, laid out in a complete mosaic, I think they would lose something. There's a magic to discovering something new, ne? But without time and effort, that feeling is debased. As for those who have already found cracky in their lives, I'm almost certain you don't have any rares, otherwise i think you would have posted them already. I can only speak from my perspective, but I don't see how it would affect them. It certainly hasn't affected me.
In short: The seasoned pilgrim has nothing to gain. The neophyte has everything to lose.
Please forgive the wall of text.
