Not sure I get the idea of using the blog for ideas that people want to share. Do you mean there will be a special blog that people contribute to strictly for ideas? I can't imagine wading through everyone's blog in search of ideas. People use their blogs in many different ways, most of which seem to be a sort of personal gardening journal. I would think it would make more sense to have a forum specifically dedicated to sharing of garden ideas, if anything. I personally preferred the format of an article and will miss that feature if it goes away. Perhaps if the site is growing at such a pace that it is difficult to maintain the existing features, it's time for some additional help?
