WordPress being an open source platform has seen tremendous growth in its usage. Along with WordPress the number of plugins being released daily has also seen a phenomenal increase. Which plugins should you use? Do you really need them?
The more the number of plugins you install, the greater is the load on the server hosting your blog and consequently slower will your website be.
Way back on January 1, 2007 when I first began to blog at WLTC, I wrote an article to address these questions. Titled Check your Plugins this New Year, the article covered what plugins you should first install.
You should also search for alternatives to heavier plugins, remove files of deactivated plugins and remembering to check for regular updates.
