I did a quick check to see what people were saying in their blogs and sample comments are
"lately there have been more and more problems, and the past two days, it's been completely dead slow".
"Bloglines just frustrates me."
"Bloglines has been having some serious problems. Often I’ll open it up and none of my feeds in the left sidebar will show. I’ve contacted Bloglines about this but haven’t received a response."
Up until now I've used Bloglines when I've been teaching RSS and encouraged people to use their service, but I'm seriously thinking of calling time on it completely. It'll be a shame, because I've really enjoyed using it over the years and have found it elegant and fun to use, but if it can't do the job it's a hinderence, not a help.
