Oh yeah talking of posts. According to my site statistics I am getting around a thousand or so clicks a week. My question is why are spams the only ones sending me comments? Please leave comments!!

Enjoy & peace!

Love is tender. Love is warm. Love is soothing like; when you have this sore tooth and you put a cool stone on it to alleviate the pain and the hard truths of life. Love comforts. Makes you forget. Love has it’s own time. Some will last for a mere second while others will live on throughout the ages. Love remembers. Love leaves its mark. Like a small scratch on a glass. No matter how you try to wipe it away it is there to stay.  And love can be wounded. It could be hurt. However love can also heal. So never loose hope.

There… My two cents on love.

It seems blogger.com is closing down it’s FTP service. Good thing I already transferred my site to WordPress before hand.

My blogging life has been quite the roamer. It seems I like my individuality. My road started with LiveJournal.com. One day I opened my LiveJournal account to find it blocked by the firewall of our school. Some people used to put their nude pictures on their LiveJournal so it was banned.  I got angry at this. Thus I transferred everything to Blogger.com. But guess what! Turkey blocked Blogger for about four to five months this got me mad. So what I did was make Blogger.com send the info to my FTP host. I even bought a domain for this host. A little coding and voila! My was site was back up and running. However this got me thinking. What if Blogger was totally banned? What would I do than? Hence I started looking for blogging scripts and that is how I met WordPress. I must say I’m very happy with it. I even integrated Zemanta with my browser to bring in even better content. In fact the picture here was found thanks to Zemanta. Anyhow…

So Blogger is closing down it’s FTP service. So what. It seems Blogger is thinking the same way. The mail they sent me states :

FTP remains a significant drain on our ability to improve Blogger: only .5% of active blogs are published via FTP — yet the percentage of our engineering resources devoted to supporting FTP vastly exceeds that.

It seems Blogger started cutting out the rotting flesh. The hoards of zombies that try to live on old tech. And this also shows Google‘s business management. If it doesn’t work, cut it out. Which I believe is one of the best ways to do management. Look at HP Labs present condition. Actually look at any big corporation. The only way you can go big is use this kind of thinking. I know… I know… It probably meant that the current FTP “engineering resources” our out of a job. But still… The show must go on.

Oh and for the people asking, the snow effect will still be here for a while. It is still snowing in Ankara, Turkey.
