As we are moving on to HTML5, there are some tags which now hold a very least importance that it did in the past.For example <dl> the defination list, I dont remember the last time used this tag.
And not only this, but there are tags which have a better and more efficient versions or just clear redundancy like <strong> and <b>, <basefont> and <font> etc.
In your Opinion, which are the tags that as a developer you can live out with?, and Which are the tags which can be ignored? because we have a better version.
It was suggested I make this an answer, so here is an excellent page that discusses which tags and attributes should be avoided in HTML5 pages, and why, though he doesn’t include elements like the
blinktag.http://www.html-5.com/avoid/
