Looks like Yahoo! pulled the plug on MyBlogLog.com on the 24/May/2011. Strangely I didn't receive the notice, but found out when my MyBlogLog RSS feed kept giving me error. I had some inkling and forewarnings some six months back when their new CEO announce major revamp to the Yahoo! web business shutting down services or selling them away. Several of their services that I was using like Geocities.com was closed and quite fortunately, Delicious.com was sold to another party.
Since I wasn't sure whether they were closing or selling Delicious I did try to back up all my bookmarks. Now that it was passed on to another company I can rest a little easy. Unfortunately the staff changeover has resulted in reorganization and the new Firefox 4 could not support their extension so I hoping that they will do soon before I'm completely comfy with Xmarks and say sayonara to Delicious for good!
As for MyBlogLog.com, I did have several of my website RSS feeds that went into it get chopped! And now I need to sort out my websites to remove their widget which is now no longer functioning.
Ah! The way dot com companies get shuffled around in the cyberworld you can never be sure who will be handling those services and thus your data and activities will change over time and you have to make adjustment for it. Just don't rely too much on each services I suppose and have contingency where possible (but sometimes it is hard to find an alternative)!
