spanish socialbookmarks links building campaign question

Hello everyone, i'm starting a backlinks building campaign for a spanish site i just created and i was wondering if you guys have any thoughts or comments about the fact of posting my site/keywords to english socialbookmarking sites as well like Diigo, or Blinklist, or if you think i would just be wasting my time, and rather try to find only spanish social bookmarking sites and post my site in those (which are less out there, trust me)?

p.s: sorry if this is not the correct section, please move accordingly if necessary

Best Regards and thanks for the help

The best approach is using a mix of the two. Although I do know that it's harder to get quality backlinks from spanish sites, they are out there, and it's very worth to spend some extra time trying to get them.
