Hi. I have been blogging on both language on separate blogs, and I can't really decide which language I want to blog with. I see both positive and negative aspects of blogging in only Norwegian or only English. The only thing I agree with is that I will have a photo blog with pictures from both work and everyday life around us. So my question is: Are you willing to read a mommy / photo blog with both Norwegian and English text? The main focus will be the pictures, but there will be a separate section with English text at the bottom.
I admin for two sites, the one affiliated with this site is my sister's blog freeprintablefun.org; but my own blog which is lifeinespanol.blogspot.com is an English/Spanish blog. I do most of my blogging in English, but made sure to have a dominate "translate button" at the top. On the few occasions that I have done similar (Sp/En) project for Free Printable Fun I do like you mentioned (sort of), each paragraph or section I do first English, then Spanish (the second in italics.)
I would read your blog with the English at the bottom. People can also go to Google Translate and enter the url and the whole page will be translated! :)
