"Thank you for uploading your OPML file. We will soon start importing your subscriptions, which might take up to several hours depending on the amount of feeds you have.
There are 22325 users in the import queue ahead of you."
It may take some time indeed... I have 114 subscriptions and some of them can be dead now, as I haven't used GR for quite some time.
Other alternatives I tried are also disappointing. July 1 will be a terrible day for the Internet.
