I would like to note the following features:
I liked the automatic filling of tags. Usually taken from the title of the article.
The only restriction that turned your attention is that you can submit at the same time to no more than 3 accounts. What accounts it will be, you choose.
For what purpose can it be used? To attract a huge amount of traffic
In my opinion, the only thing missing in the functionality is the availability of automatic registration of accounts in the supported social bookmarking services. But this is most likely a matter of time.
In order not to allow social bookmarking services to be completely clogged, the service was paid. Cost - $ 15 / month.
* For publicity.
