Good news from Google Maps team again. Recently I've found api for Flex. This is a great advantage for actionscript developers. First of all, I've already mentioned that JS api is a bit slow thing... And specially I though about Flex/Flash maps API ( like Yahoo maps provided before ). And right now we have it.

At the first look not so "super" like JS api. But this is a big hit, I think.

Google maps one of the best mapping API. But sometimes you don't need navigation, zoom and other cool stuff. Sometimes you need something simple. Simple and fast. Yes, google maps makes a page a bit slowly, a bit big, just because this is maps. Looks like guys from Google understood this. Sometimes you don't want to load all the tiles and JS API. You just need to show some address or route on the map. And here static maps can help you. Static map can show simple markers and even routes.

Every webmaster knows that Google is the king of generic traffic. And this is very important to be on good place in Google. 

Google introduced new option for webmasters: Geographic targeting... It looks like a good news, because now you can target you site to specific location. But, there are  bad news, the sites with regional domains (.uk .us .dk) targeted on these countries by Google automatically. Does that means that now if your site targeted world-wide but historically hosted in some regional domain lost visitors? Currently we have no answer about this, but I think this can affect traffic of sites that are hosted on regional domains.

Bad in this new feature of webmaster tools that you can't change geographic targeting for site located on regional domain. You'll see the following message

"Your site's domain (.XX) is already associated with the country/region: XXXXX"

This info can be interesting for owners of regional domains. You can check it in Google Webmaster Tools

I've currently mentioned that one my site on regional domain affected by this change. And I'm thinking to move it smoothly to some .com .org or .net domain to be world wide. So, don't locate your new site on regional domain, better longer, but world-wide.

Google Gadget for you site to show geographic location of visitors. Nice thing for registration pages, comments pages. You can put this Gadget on your web site.
