OK, let me tell you guys some facts here
> Googlebot and other bots will visit your site when THEY feel like it - not when you tell them
> Sometimes Googlebot will have a rest while Google is compiling new indexes (ie: dont get more stuff whilst the compiler is running)
> To get a site spidered more often you need a high
PR - in general sites with a
PR of 5 or above should get visits every 2 days (obviously if a site is more important Google and others will come by more often)
> A robots.txt file can do some damage if you set them up incorrectly (search for robots.txt in google) you do not need one of these -- only really to keep away unfriendly bots or to tell spiders what not to index (like private sites etc)
> As for having robots.txt files in the "root" of hosting companies .... well, I can't swear on this board but suffice to say that is incorrect
Get more links and your
PR will increase (well, links from good sites)
Get more links and googlebot will follow those links so will visit your site
Trust all this helps and trying to put some myths to rest

PS - oh yes, back to the original question. YES, MSN, Y! and Google will include the most relevant snippet in your search engine listing -- most times this IS what you put in your meta description tag -- However, Google has recently been adding in your description from your listing in DMOZ (if you are listed there) -- but changing your description could improve your click throughs,
