I have lately been inundated with popunders from the sites I surf. At first, I thought it had to do entirely eith the sites I surfed via blogexplosion and blogclicker (as I run three separate windows when I surf).
But as I went across another JU blogger's site, it became clear: SOME of those popups, at least, are coming from JU blogsites (before you ask, I don't have the option of downloading software to kill these pesky mosquitos...it's a library computer, 'member?).
I realize that there are some among us who have the quixotic dream of making vast fortunes off of surfing the internet; frankly, I tend to be among them from time to time. And I even ran popunders on my sister site for a brief period of time.
But eventually I realized that popunders are the bane of a websurfer's experience, and in some cases, can potentially cause a surfer to abandon your blog altogether; thus negating any positive benefits you may have gained from the popunders.
So, please, give it some serious consideration...and give my poor mouse a rest from these annoyances!
