Is it need ?

If I do bookmarking is it necessary to change the description every
time or else I continue with same one .Plz give your Idea?

 

Its better to change the description and make it as compelling as possible

 

The Title and Description should be unique and meaning full.

 

I'd recommend you to go for different Title and description. Google will index you better and your pagerank may incerase as it will look like different people have bookmarked on different SB sites.

 

i completely agree with fundu

 

I think it's better to go for 3 or 4 titles and then rotate them for every submission..And coming to description, i think it's not a good idea of changing description continuously..But anyhow you go for it and check out your results and then you will feel the difference..Thanks for writing..
