Hi Lisa,
I personally think your blog is fabulous!!! I'm following it now (but I don't show up as thebellefleur - I show up under my blog name (thehandcraftedcottage). I left a comment on your last post too! :)
You know what's so funny - as soon as I saw your blog I was like, omg, how did she change the font to that? I was going to ask you because I can't figure out how to change the font from the basic 4 options they give you. Perhaps the random was talking about the colour....like, they thought the pink on light pink was hard to read? Personally I think it's fine but maybe they are older (or slightly hard of seeing????).
Anyways, I love the blog and if you like your font, I would totally keep it!
Here's a link to my blog (I did a feature on Team Posh Nursery two posts ago)
