this looks like a fine thing...but, i have some constructive criticisms...
adding is too difficult...check my previous post about "bookmarklets"...in general, i don't think a user should have to visit the site to insert a new bookmark...just have a popup that grabs the page information and the page title...then the user can either change the entries plus do categorizations (if they want)...
you should add the option (which you could also make available through another postlet) to allow people to create a popup window with the links list. then, when clicked they would refresh the parent window instead of opening up new windows...
what's with that logo? and i won't even comment on the interface...
printing them is nice, but why? why not have an exportable list that could be imported back into browsers?
sharing...why not setup a feature where people could share lists ( "sharelets" ?) that could possible be specific to certain topics...like a sharelet of php forums or php blogs, etc...obviously people would have the option to share or not to share...
which brings up an idea of categorization and such...what if people want to categorize and subcategorize their links?
moving, changing and deleting links...this could be done better...people really should not need to know id numbers to do these kinds of things...
