Zigtag had recent taglist numbering 1063 links though it required login. Blinklist displays tagcloud without login, so needed to synchronize the two. Exported blinklist to .htm for backup then deleted all links.
Zigtag exports to bookmark .htm file. Blinklist import saw links, but only tag shown was “Imported”. This also occurred with its own .htm backup file.
Workaround was to use del.icio.us by exporting tags for backup, deleting account to avoid having to remove links singly, then recreating new empty account, and importing zigtag .htm file which showed tags okay. Deleted Zigtag_Imported_Bookmarks tag to minimize clutter. Blinklist import has mode to source from delicious. URL was not recognized until removed trailing “?”, then could login, and displayed links in XML format. Saved to file, then imported to blinklist which now recognized tags okay in list and cloud.
