Russian: What does the expression "Вот тут" mean?

Question

I understand Вот means something that is coming into view - Вот Анна! :: Here's Anna!

and I understand тут is the same as здесь , which means "here", at a particular location.

But Ive noticed a few phrases on the internet beginning with Вот тут ..

For example,

Вот тут я сижу часами on Flickr

Why not just say:

тут я сижу часами on Flickr

??

Do Russians commonly use this expression Вот тут ?

Thanks again for your help!

Tracy.

Answer 1

BOT is used to show a place closer.

Anyway BOT TyT is a spoken language,

The official word to say "here" is 3DECb  

Answer 2

Тут = here

Вот тут = right here

Just put your signature right here. — Распишись вот здесь.

You can say also "прямо здесь"

Answer 3

Probably linguists answer better than me.

In your example, the meaning of the same.

This synonyms. The word "вот" simply reinforces an indication of the place.

But you can not use it.
