15 Twitter accounts to follow ... one year later
One year after monitoring 15 Twitter accounts, we have made an update of what has happened. 
The chart does not include the first two accounts, because their reach level affects comparative visibility.
Two of the accounts did not come to life, despite their importance at the time of the first comparison. For the following analysis we will include other accounts that have grown sustainably, it quickly comes to mind @mappingGIS Which at this point already has 1,110 followers, more than those who have some of these accounts that we have monitored.

Bit by bit Twitter has come to fill a space that the media does not cover equally, especially for short topics, links and information in real time. With the same or worse disadvantage of going to the abyss after a couple of days, but playing an important role in the Dissemination of themesAnd management of followers. Here is a list of accounts in the geospatial area that should be followed; Some of them are media, others are accounts that add to the topic.
They are sorted according to followers, to April of 2012, the first two take almost the 50% of the 30,000 followers that represent in total the 15 accounts. Updated on red to August of 2012 and I have added a column of how much followers have grown in these 5 months.
The table does not change much but it can be seen that some sites have a slower growth than usual, such as URISA, Comunidad IGN and CamptoCamp. Spatial Sustain appears to be unavailable. Atctualized in magenta To December of 2012.
The trend remains at the top, it stands out that PortalGeografos, Mapping Magazine and CamptoCamp change positions again. And for some strange reason, Vector_One is not available after the creation of the LMA.

The table at the beginning reflects the update to May of 2013.
Very good, apparently you are very creative when creating a post like this, I will follow the accounts, that if you do an update to keep us updated.
@JosefinaAymara, I follow todosssss!
Thanks for the observation.
I made an update to 31 for August of 2012
Great your posts are very good and out of the ordinary, interesting to know who to follow by twitter.
It would not be bad if you do an update of the followers, remember that many win followers, maybe others lose.
cheers.
Of course it's vague.
In this case it is used to order the followers of the people I follow, more clearly it is not the same as having “followers” than “readers”. Bem-vindo, a major study.
I do not think that the number of followers is parameter to determine the importance of a profile on Twitter, this is vague. As stated above, celebrities have thousands of followers, as well as companies, brands and websites, but they are not relevant, that is, they generate really important content or have a good relationship with their followers
How do you evaluate the relevance of a Twitter? For your constancy? Because of its originality? For your content?
Did you paste an account and observe that she had 30.000 followers, but she followed 29.000, so does this profile say something? Isso not an “exchange of favors”?
It is very, very vague to determine the importance of profile based on number of followers. It is necessary to define a series of parameters to get to what really matters: relevance and importance.
Is not this how Google does with your websites?
Agree.
I clarify that I have used the number of followers to order them in descending order. If I did it for relevance ... it wouldn't be that simple.
The number of followers does not say much. A company or a celebrity has millions of followers, but who said tweeting relevant?
Many people do not self-promote and interact with followers.
What matters is the relevance and the profile to show good content. The number of followers is the wind.
The Web that has helped me most in terms of content, even though its founder and former collaborators do not stay as active, is:
http://www.gabrielortiz.com/
I have observed duplicate subjects, for example, in Cartesía and where they answer is in the first one. On the other hand, I work with free software (especially GRASS-QGIS) and in Spanish it is very difficult to get information. However, recently I discovered a website:
http://geotux.tuxfamily.org/
Which links to content that uses free alternatives.
Very good. Some accounts I did not have. @geoinformation
http://twitter.com/geoinformacao
The truth is I follow some of these accounts, I should follow the others.
Good contribution, although note the best content I found in Cartesia, Geofumadas and the blog of Franz, it would be good to help us with Twitter accounts or Facebook of them, do not know if they have many followers, but actually have excellent content .
