Continue to tune and improve geocode performance. 

Better recognition of datelines and non boas-city explicit addresses.

I ran an import (v.84) and spot checked a couple result. In this one http://www.boston.com/news/local/massachusetts/articles/2009/04/09/mass_liquor_store_offering_home_
delivery/?rss_id=Boston.com+--+Local+news

Dateline is Beverly, MA but tagged Boston...this was in the Boston.com news RSS import.

This one:
http://www.boston.com/news/local/massachusetts/articles/2009/04/09/mass_daily/?rss_id=Boston.com+-
-+Local+news

Dateline is Braintree but tag is Boston.

This one:

http://www.boston.com/news/local/massachusetts/articles/2009/04/09/partners_healthcare_passes_new_li
mits_on_gifts?rss_id=Boston.com+--+Local+news

has Boston dateline but no tag.

I know it is an ongoing thing, I just wanted to give you some examples for tuning...

Another use case you might want to tune for...

I set up a Yelp feed in Boston, which has explicit addresses for businesses o the top of the page. I tried it with 
Strict settings and got almost no matches. With loose settings, I got either Boston or things mentioned in 
reviews as opposed to the business listing address.

Here's and example of one that was tagged as Boston;

When you geo-bias it to a city does it make itself aware of nearby city names for pattern matching? that is what 
we did in teragram -- by saying that this was Gainesville content we looked for the couple dozen city names in 
the immediate vicinity... If the PL algorithm is doing that it doesn't seem to be doing it well as it rarely seems to 
find other cities beyond what it has been biased for.

if it does what i've described, after recognizing the proximate city ideally it would look for an address or place 
reference within a word or two of the city and use the proximate city as the bias for recognizing the address.

Disallow patterns for "Is Street" (as in is street violence ruining...) and "Toy Drive".

The geocoder seems to tag single address multiple ways -- 100 Main Street and also Main Street
