Everything looks good, the degree of customization is pretty good, but what users really need is the ability to import the previous bookmarks. Maybe there is one, but I couldn't find any way to import my Firefox bookmarks. I don't care how crude it might be since I can reformat once they are imported, but it really should have the funtionality.
[Edited] Thanks for listening to my suggestions! I replied too late, but it works as it is supposed to :)
Started using mymark.me since last one month and I have noticed that they are improving in a ways which helped me a lot with few new features such as notes and it is really useful to keep my information handy on just one page.
