Flock may be affected by the Yahoo/Microsoft deal, since Flock partnered with Yahoo to get paid for searches using the default Yahoo search box.
I’m sure everyone has heard about Microsoft offering to buy Yahoo.
When we trust our data to a site like Flickr, we trust that it will always be there. I’m not predicting that they’ll disappear, but if they do, our data will also be gone.
As an alternative to Flickr, I may switch to either Zooomr or Picassa. I’ve had Picassa for a while, but I never really used it until I got my Eye-Fi card and set it up as the default upload site.
For del.icio.us, the alternative seems to be be ma.gnolia, which I signed up for a long time ago but pretty much forgot about.
